My take? The "average" woman is more physically attractive than the "average" man, to men and women, st8 or bi. Mrs. knb looks fantastic wearing a thong or other lingerie, were I to try that, while I wouldn't necessarily cause people to want to gouge their own eyes out, neither is it nearly as easy on the eyes. Course I have a tendency to run around completely naked, where appropriate of course.
Well, those posts are not made by swingers. They're made by swinger wanna-be's who do tend to be male more than female. Why is that? My opinion is that it's got more to do with classic vanilla thinking than swinger. Most of us, even those who choose the Lifestyle, were taught that sex was a sacred, yet at the same time awful thing that was to be done within the confines of a bonafide marriage ONLY!!! We teach women that if they like sex tooooo much they're sluts, or whores. Many, perhaps most, are taught that masturbation, oral sex, or anything that doesn't involve a genuine attempt to procreate is bad, wrong, gross, sinful, or all of the above. This message is given to women so much more so than men which is why, IMO, the "average" woman becomes more sexually repressed than the "average" man and explains the disparity. If a man wants to have multiple partners, well that's just boys being boys, the minute a woman is even OPEN to the idea, much less enthusiastic about it they are the worst kind of slut there is.
I think the idea that women are inherently, genetically, biologically less interested in sex is hogwash, rather I think we train them to be that way.
I also think to some degree that explains the disparity of why single female swingers are desired, and single men are not, but is not the full story.
I think many single-males who self identify as being a swinger are really not. They're simply out to get laid, pretty much do not care by whom, and figure hanging out with swingers is an easy way to make that happen. Many, but not all of those types are too jealous and possessive to be a true swinger, and if and when they get into a relationship, at best will be totally monogamous, at worst will expect monogamy from their SO but will continue to have their own flings.
So, you combine the learned sexual repression that many women are afflicted with with single guys just looking for a piece of ass and the result is imbalance. Personally, we are not interested in going to an event or club where it's 80% men.
