I think when it comes to kinky sex women are just a kinky as men but they are embarrassed by it not many women are as accepting of there kink desires and fantasies as the wonderful ladies that grace this site. I guess it comes from social conditioning. It is a fact that women from more liberal countries having grown up with more liberal attitudes embrace sex much more freely than those from repressed and religious countries that see sex as dirty or shameful. I have found that far more men admit to being a bit kinky to fellow men and women than women do. Is it that men are better at overriding their social conditioning.
There is also with the majority of women and I don't mean this in an offensive way, to follow the heard. Advertisers have used the fact for many years to sell things. Look at fashion, many women won't be seen dead in something that was last years fashion were men will wear their clothes to destruction. Women are very much ago with the crowd, I don't want to stand out type. Take my wife for instance ( no, really do take her , lol. just kidding dear.) She works with a bunch of other women and I always know when there is a new fad on the go because my wife will have to have it as do all the other women and before you know it they are all looking, talking and doing the same thing.
You take two women talking both of them have secret kinky desires, one day one the first women gets brave and brings the subject up in conversion. The second woman due to her social conditioning and embarrassment puts the subject down not because she has no interest in it or wishes to learn but because she thinks it isn't the done thing she doesn't want to stand out as being different to the normal. Now the second lady retracts on broaching the other subject. Now that second woman when she meets a third woman who also might bring up kinky sex in conversation then kills the subject dead because she thinks that is the norm. Look at the fifty shades of grey book/movie once that had become a fad many, many women were happy to admit they fancy a bit of bdsm that wouldn't have even dreamed of admitting such a thing before.
If it became a fashion tomorrow for women to post photos of naked men on the web we would be inundated with women willing to post naked men but until it seems the norm for women to express themselves in such a way it won't happen.
I have known women that actually wanted to and enjoyed exposing me and to my cost, there have been a few that took it far further than I thought. Some of it was to do with power exchange games and or them wishing to embarrass and humiliate me because that was their kink and I found that once one woman admitted to enjoying it then suddenly she had a friend to whom she had sent my photos and she was posting them and wanting more.
Then there is the fact that it is usually a submissive act to have one's photos exposed to the world, it is giving the exposurer/dominant a sense of power over you and as there are far more submissive women again due to social conditioning than dominant ones you get an imbalance.
It is only because of a few brave strong female individuals that have come out and said screw what society thinks this is what I want to do and I'm going to do it, that women have come to the fore in sexual kinks.
Personally, I will always be on the side and help any woman that wants to break free of societies repression and be and do as she really wants to.
Speech over, now the neigh sayers can come out.
