Blackbirch, you're right, d/s leanings are more innate than cultural. According to A Billion Wicked Thoughts (Ogas and Gaddam, 2011) and its original reference articles, most (80-90%) straight men are naturally dominant, most (85-95%) straight women are naturally submissive. Also, about 90% of men are kinky, but only about 15% of women are, so that's a problem. These numbers bear up across countries, apparently, as far as they've been able to test.
There's not much research out there on kink, so your original question is difficult to answer, but here are my guesses:
Why is there way more m/f out there? - The vast majority of people who watch straight kink videos online are men (see figures above on kink...) - The majority of the makers of kink videos are men - So the vast majority of straight kink films will feature dominant men (cuz 90%) and young women and girls (cuz men like pretty young women), because it's made for a majority male market.
The other part of your question (why no videos with older-ish F and young M?), beats me. There's craploads in gay porn (20-year-olds getting spanked by 40- and 50-year-olds, that is), but nearly none in straight porn. Why? Dunno. Most women don't want it filmed and put online, maybe? Why not? Dunno. (I mean, I know why I don't, but I don't know what anyone else's reasons are.)
Overall, if I ever HAD to film anything - don't want to, but if I had to - and had a choice between appearing in a video as a sub or as a dom, I'd pick as a sub every time. Not quite sure why. |
