Why do guys want to fuck a married woman like me?

I get so many lovely and very sincere messages from guys who get really turned on by the thought of fucking a mature married woman like me. I’m trying to understand why guys get so excited by these thoughts and what is it that makes it so much more pleasurable for you.... say compared with enjoying a younger single woman? I’m not complaining of course, I think it’s wonderful to hear your thoughts but I’m trying hard to understand and explore the phycology going on here.
Is it a taboo thing knowing you’re fucking a woman who belongs to another guy... sort of unattainable? It’s certainly true I know what I want and what I enjoy but so do many confident women, and with divorce on the rise, there does seem to be a greater number of newly single women ‘on the market’ looking for sexual pleasure, but for some reason some guys I meet really do get excited and aroused thinking about fucking a real life married woman!
Please, please tell me what’s the attraction.... after all I’ve got a chubby figure, a well used cunt and my large 38” breasts are starting to become saggy.... let’s face it, I’m not exactly young free and single am I!

Guys who know me are fully aware that I have a very understanding husband who of course enjoys my curvaceous body but also encourages me to experience other sexual pleasures outside marriage to satisfy my inner physical and emotional needs and desires. We often mix with friends and acquaintances sharing sexual pleasure and Marc loves it when an interested guy or guys ask him for permission to fuck me and perhaps spend the night with me. It’s a very exciting thought letting him choose sexual partners for me...... even choosing if they have to use a condom, or if I’m very lucky, allowing me to be fucked bareback... it’s like a gentlemen’s agreement and to add to the excitement, I don’t get to know in advance... so I never know what to expect!

With regular marital fucking, there is always a degree of familiarity where Marc knows what I like and how my body responds, but I find sharing my body with complete strangers so much more exciting... there is no familiarity or preconceptions, it’s like unknown territory to explore and of course I want to satisfy in any way I can, sharing every little detail with Marc later. I have even talked to him on the phone when I’m being pleasured to add to the sharing experience!

I’ve never been impregnated (despite numerous breeding sessions with different partners) so my vagina is still quite satisfyingly tight and toned. I’ve got good vaginal control when I’m being penetrated, but my body is staring to show the signs of ageing. I’ve put on a few pounds and my large breasts aren’t a firm as they used to be and starting to become saggy, but I’m willing to try most things so maybe I’ve still got plenty to offer!

I've received some really interesting and diverse replies from guys, everything from the pleasure of mixing your semen with my Hubby’s, through to self-loathing, knowing you’re never going to be as good as my husband which is of course is absolutely not true! In fact many partners have shown me sexual pleasures that I could never have experienced before and certainly not with my husband. I love every aspect of sharing my sexual pleasures with different guys of all ages, younger and older and just occasionally I have enjoyed the ultimate pleasure of an attentive threesome or group activities. It has also been suggested that mature women are more likely to do anything to please and are more desperate! I’ve been told I have a body built for sexual pleasure and I love giving satisfying pleasure to guys.
Quite a few guys have picked up on the 'unattainable' aspect as being a strong motivator, but what I would say is the my lovers are usually married themselves and mostly have the ability to separate their sexual desires and passions while offering the experience of a married partner then walking away. Other people have expressed a desire to send me back home to my hubby fully inseminated with a vagina full of their semen as a sort of gift or demonstration of temporary ownership. Guys often expect me to offer things their wives won’t consider which may be the attraction and sometimes they want to continue a sexual relationship with me as a substitute to their own marriage like a temporary wife. I'm very honored to fulfil the role of a surrogate wife to my partners and I do like to spend time fulfilling and developing this role to make them happy. Its true that some guys have fallen in love with me over the years which I guess is inevitable with relationships and has been a wonderful pleasure for me without compromising my own marriage.
So please let me know your thoughts and I’ll be happy to reply
