Cuckold: (noun) a man who has been knowingly or unwittingly cuckolded by his wife or partner's act of having sex with another man (men), or who actively solicits his wife or partner in entering into sexual relations with another man (men) for either her gratification, or his, or both.
A cuckold may be depicted as wearing horns, these being the horns of rutting stags which lose all rights to their mates when successfully challenged by the new alpha male; or the horns of “the old fertility gods” belonging to an age when society was thought to be matriarchal, or at least was not as strongly patriarchal as it became, (men thereafter, for a long time being encouraged to beat their wives into submission, or even murder them out of hand for adultery).

Cuckolding: (verb) where a libidinous woman (sometimes referred to as a “cuckoldress” or “hotwife”) cuckolds her husband by having sex with another man (men) with or without his knowledge or consent.

Cuckold lifestyle: Where both parties in a marriage or relationship actively seek for the woman to have sex with other men, for the woman's gratification, the man being gratified in that knowledge. These other men may be lovers, boyfriends, or mere sex objects. They may live within the household as members of the f a m i l y or as lodgers, or they may visit the home for sex, or meetings may be arranged elsewhere to keep the relationship secret. The husband may be present and participating, present as a voyeur, sometimes in concealment, and occasionally as photographer, or may be absent awaiting his wife's return. Where the other men are mere sex objects (“bulls” and “studs”) they may be found by either or both parties, amongst work colleagues, in clubs and bars, on the internet, or in public places (see dogging). Anonymous sex with total strangers is often actively sought, swingers clubs hold "greedy-girl nights" for this express purpose. Often unprotected sex (even occasionally pregnancy risk sex) is sought, the husband getting to "clean-up" his wife with his tongue either in the presence of the lover/stud or when the wife returns home after her adventure bearing the evidence of her heroic shamelessness on her body, or in her knickers.
Some elements of “the lifestyle” include a humiliation fetish for impotent or under-endowed husbands in a femdom relationship which psychology regards as a variant of masochism, but this is not the general rule. The Psychologists seem to be labouring under the outdated premise that “men are men” and are supposed to keep their women in order! “Cheating” on their wives being a male prerogative, and for men to allow their women to “cheat” on them must therefore reflect badly on the men. They have not yet fathomed that multiple partner sexual relationships are the ancient societal norm and it is monogamy which is in fact the more recent aberration (see article “Outcest Yesterday, Swinging Today”).
Where photographs are taken these may be proudly displayed on the internet on dedicated cuckold/wife-sharing sites; the largest United Kingdom site having one hundred and twenty-three thousand members, equivalent sites in North America having over two and a half million.
“Wife and Girlfriend Sharing” sites are also popular, are more-or-less the same, and seem to be a reaction against the sad humiliation fetish which some see as implicit in the term “Cuckolding”. It may also be a reaction against the cuckold sites emphasis on inter- racial sex, where the “Hot-Wives” are supposed to seek BBC (Big Black Cock) to the exclusion of their white partners.

Cuckolds collective noun:-
an “incredibility of cuckolds” (from other men finding their desire to be cuckolds incredible)
a “conspiracy of cuckolds” (relating to secrecy for those who have not “come out”)
a “devotion of cuckolds”
a “deference of cuckolds”
a “duty of cuckolds”
a “ministry of cuckolds” (the last four aforementioned relating to the husband's duty to see his wife's needs fulfilled by all means practicable)
a “glory of cuckolds” (relating to the husbands pride in the glorious shamelessness of his wife, his love and continued devotion to her)

Cuckolds “come out” from:- "the wardrobe" (here deferring to those who watch from concealment)

Swinging (noun) is a non-monogamous behaviour, in which partners in a committed relationship engage in sexual acts with others as a recreational or social activity.

Swinging (verb) can take place in a number of contexts, ranging from spontaneous sexual activity involving partner swapping at an informal gathering of friends to planned regular social meetings to “hooking-up” with like-minded people at a swingers' club. The term “swinging” is more commonly used instead of the older term “wife-swapping”, which has been criticized for being androcentric (assuming men to be in charge).
The phenomenon of swinging, or at least its wider discussion and practice, is regarded by some as arising from the freer attitudes to sexual activity after the sexual revolution of the 1960s, the invention and availability of the contraceptive pill and the emergence of treatments for many of the sexually transmitted diseases, although it can be shown to be much older than this. It is also discussed as a return to the ancient societal norm of “outcest” and other multi-partner sexual relationships such as polyandry and cuckoldry which were prevalent for half a million years or more prior to the introduction of the monogamous paradigm and the male fetish for virginity and constancy, which sought to guarantee inheritance in the male line, and became embedded in religious ethic. There are many records of couples over the last couple of hundred years at house parties and elsewhere, where both feel free to philander so long as the wife has supplied her husband with “an heir and a spare” and bastards are thereafter just accepted into the f a m i l y. And records of hosts having to invite lovers and mistresses as well as the husbands and wives of their guests; where a lady must have a husband for the name and a lover for the game.

Swingers, collective noun:-
an “adventure of swingers”
a “shamelessness of swingers"
an “anonymity of swingers”
a “conspiracy of swingers” (relating to secrecy amongst those who have not “come out”)
a “keyring of swingers” (from the old “wife-swappers” practice of picking a bunch of car-keys out of a hat or bowl and going home with the wife belonging to that car, originating in the 1930s)

Swingers, “come out” from:- THEY DESPERATELY NEED A SUITABLE WORD FOR THIS

Prostitute: (noun) a person (usually female) who trades sexual favours for financial or material gain. (see also hooker, whore, tart, trollop, strumpet etc.. - female, all derogatory; catamite, sodomite, bum-boy, etc.. – all male)

Prostitution: (noun) the act or trade of exchanging sexual favours for financial or material gain. (From a legal standpoint there is no satisfactory way of drawing a precise line through the range of behaviour from a prostitute soliciting strangers for cash in the street, to the happily married couple where the wife trades matrimonial intercourse for a raise in the housekeeping money! The more civilised jurisdictions therefore, restrain their laws to crimes concerning public order – soliciting in public places, soliciting on licenced premises, kerb-crawling; and slavery related offences, living off the earnings of a prostitute, and human trafficking.) Prostitution, where women offer their services to men, is by definition a form of polyandry, where a group of women sexually service, and are financially supported by a significantly larger group of men. Some prostitutes will jealously guard a special client from falling in with her s i s t e r s-in-sin for financial reasons, but most accept that their punters want to play the field and discuss, pass on and recommend clients to each other, trusting that their s i s t e r s will return the favour. Better and safer to have a client come recommended than to have to cultivate another total stranger. Similarly, the occasional client will try to persuade themselves that “their girl” is seeing them exclusively, they just tend not to talk to other clients. However, most clients too will discuss, pass on and recommend girls to each other, often with a degree of pride in recommending the excellence of a particular girl's services.
The sheer “normality” with which prostitutes treat and talk about their profession never ceases to surprise observers; with reference to “work” and “wages” and “doing the business”. How openly and casually they discuss their punters, what their punters are like, what they ask for, just how quickly they can turn some of them around; their payments and services; (these last two not always honestly – not wanting to admit how little they may have charged, or the level of service provided – should their s i s t e r s look down upon them).
We cannot avoid being concerned about the horrors of human trafficking, slavery, threats, v i o l e n c e, k i d napping of c h i l d ren, withholding of d r u g supply, imprisonment, public exposure and vulnerable abused c h i l dren being groomed, all by greedy boyfriends, pimps, criminals and criminal gangs. Everybody, police, social workers clients and the prostitutes themselves, need to work tirelessly to eliminate these abuses, the legislators need where necessary to change the law to make the abusers more amenable to it. This is why many prostitutes are so vehement in telling everyone that they are “independent”. Punters can get personal satisfaction from “helping a girl out financially” but hate to think that their money is being taken by some cowardly, violent pimp lurking in the shadows.
A significant number of clients seek to have unprotected sex with the prostitutes they pick up, probably more than half; and there are enough girls prepared to provide this service to satisfy the demand. The clients' motivations are various. Some may have difficulty maintaining an erection while struggling with a condom (professionals have developed the “four finger stretch” and the knack of putting on a condom with their mouth to cope with this). Some may seek the satisfaction of feeling the bare skin, and may need this to help them maintain an erection. Some just get off on the risk, like those who embrace the risk of being caught having sex in public places, and this too may aid with getting and keeping it up. While the older clients may have difficulty with prompt and sustainable erections, the young bucks who have no such problem are just as keen on unprotected sex. Picking up girls for sex can be a competitive business, old or young; guys talk about it to each other. They compare notes on the girls they meet; they brag about how good a girl is, how “dirty” she is, what she will do for them, how cheap they are, or how generous a patron they can be for a particularity lovely, particularity enthusiastic, or particularity dirty girl. Clients brag about having unprotected sex, and if you aren't prepared to take the risks, you're just a woose!
Some men actively want to share their women. If internet sites are anything to go by, there must be millions of men worldwide in Cuckolding, Wife and Girlfriend Sharing, and Dogging groups. While, on the face of it, these groups seek to share the women they love with other men, friends, or strangers, or both, a high proportion do not have cooperative partners prepared to do it with. Surveys suggest that while twenty percent of men want to get into the “swinging” scene at some level, only two percent of women do; even then this suggests that there are “secret swingers” in one household in fifty, at that rate, one on every street in the country.
Prostitutes have got in on the act. The main e s c o r t sites offer Cuckolding and Dogging as activities which can be paid for by a client. The girl will be your partner-in sin for a party or a dogging mission, and even though you have to pay her, no money will be seen to change hands (and the client is going to have to pay for all her encounters during the event). The client is seen by all present to be generously passing his “partner” around, possibly in a melee, with semen flying in all directions, because cuckolds and doggers demonstrate an even higher than average interest in unprotected sex. Swingers' parties and such events are usually secure in a private house or a hotel room. Being caught by the police apart, dogging is a remarkable safe environment due to the sheer numbers of strangers involved, none of whom know each other well enough to lie for them; they are all very polite, ask permission and take “no” for an answer – which will not necessarily be the case alone with a paying client in an isolated place. While taking a prostitute out to swingers' parties or cuckolding or dogging may be an expensive, minority pursuit; sharing them is cheap and easy, if sharing is your thing. Only the most deluded client who is seriously in denial believes that the girl he picks up is about to be faithful to him! Clients are picking up girls who they know are having sex with other men, sometimes with large numbers of men. The men tell each other all about it and there is little difficulty getting the girls themselves to brag about it. A client knows that he is sharing a prostitute with the man he passed in the hallway, or whose car she just got out of. She won't wash if the client wants to enjoy the aftermath and asks her not to. She will probably arrange meetings for him with like-minded clients where they really get to share her in the one bed together, she may even give them each a discount on her hourly rate.
The prostitutes motivation for having unprotected sex with their clients too, is various. It can be sheer stupidity, there is no intelligence test for being a prostitute. Women have been silly enough to believe that they can't get pregnant or an STI if they have sex standing up (as if gravity had anything to do with it)! Just because someone who sounded authoritative told them so. Often their colleagues tell them that they've been doing it for years and have never caught anything. Their clients beg them for it, tell them it's safe and that all their friends are doing it. And there is the money, but not all girls charge extra. Some may leave home or the pub without any condoms and pick up a client, they may say they were only expecting to perform oral sex that night. Faced with a client with money in his hand asking for penetrative sex, they may just tell him to “tear away” do it without, rather than waste time buying condoms and risk loosing the business. This is a “Just This Once” scenario which turns into “Any Time It Suits”. Extended periods without getting an infection leads to complacency and doing it “All The Time”. Occasionally a prostitute working and without condoms will face a doubting client, here the reasons why having sex with her “is safe” are also interesting. Simply “I'm clean” or “My boyfriend or one of my regulars would have told me if they caught anything from me” or “I go to the clinic” or “That's why you're paying me extra, to know I'm safe”. And of course there is always the money; however it is not only the d r u g addicts desperate for a fix, or the alcoholics needing their next bottle to crawl into; there are the gamblers, shoppers and party-goers who have blown everything and can't pay the rent, can't feed their c h i l dren or can't afford the taxi home. And surprisingly there is another safety factor; it is almost certainly safer to have unprotected sex with half a dozen regulars you know and trust, than to go alone to some dark place with a total stranger.
How do these girls get into the business in the first place? We would all like to think that a girl who loves having lots of sex, has turned her hobby into her profession and is thoroughly enjoying herself! We all hope in our hearts that there really are girls like that out there (if there are, they are mostly in the upper echelons of the “e s c o r t market”). Many women feel empowered by the attentions of men, and may also feel empowered by being paid for their services; a phenomenon which increases amongst those with low self esteem in the first place. In reality much prostitution is sexual drudgery; sadly it so often tends to be a matter of the girl gritting her teeth and putting up with it for the money (also sadly there are marriages like that too). Frequently these girls are single parents with limited c h i l dcare support, they can get a babysitter for a couple of hours in an evening which is no use when it comes to holding down a job, but can be a lifesaver financially when it comes to “doing” a couple of punters. There are also matters of financial mismanagement, reliance on loan sharks and pawnbrokers, partying and of course addiction, all of which makes them more vulnerable, all the more in need of a quick “money fix”.
