Cuckold

"A bull can certainly deliver physically satisfying sex, but the mental/emotional needs of a cuckold couple require a Dom.

So many feel a Dom is synonymous with a bull but there are very important distinctions. A Dom is a bull who has grown beyond only a sexual role and attained an awareness of the mental and emotional implications of his inclusion in a marriage as well as experience in what to do with that knowledge to better benefit the couple and not just himself."
