Before the term 'cougar' got its extensive mileage in the last few years, there were always young women around who cottoned on to the fact eons ago that with age comes experience. For every cougar bait that's been floored by the seasoned talents of an older female lover, there's definitely a kitten or two out there that have enjoyed a mature male playmate.

Most younger women will have had sexual partners around the same age as them and to be honest, not too many guys under 25 have received distinctions in Female Sexual Pleasure 101. I think most feel that knowing roughly where the clitoris is located is sufficient qualification. In their defense, not too many girls their age have the confidence to tell guys what to do either so it's little surprise that some young guys think they're doing everything right (until Stifler's Mom sets them straight anyway).

I'd say there is a similar element for younger women. There's certainly the thrill of being in the hands of someone who knows what they are doing (well you'd hope so by the age of 40...) and then there's also the ego boost of being told by an experienced lover that they're giving good head.

If you've managed to wow a 25 year old, then good stuff. Keep wowing her and hopefully if she should consider shagging a guy her own age again one day, she can give him some pointers to impress a cougar with. Ahhh.. The cycle of sexual learning.

As for domination, I think a good number of men enjoy a bit of domination as well. Since no one really thinks of BDSM or Dom/Sub play as being super deviant these days, I'm inclined to think that both men and women feel OK about admitting to having interest in fetishes and other fun things. In short, I think many people have have always had some interest in being dominated but it's just less awkward to admit it and act it out now.
