I don't want to wade into the argument that seems to be going on, but I think there's been a lot of sense written on this thread in places.
I know there are men who love to give pleasure. I also think that a lot of it's about good communication - and, yes, I think that it's better if a woman can communicate what feels good. It's not a 'obligation', somehow putting the responsibility on a woman - but, hey we're a little more complicated than men and therefore a little guidance is useful. But that works both ways, I love a man being able to communicate what's feeling good.
What intriges me is that this is one of the first threads I've found that seems to be accepting that people with a past of sexual linked abuse (childhood or rape) can continue to have and build a healthy sex life. I think that's really positive - I was starting to feel like a weirdo.
Hmmm, not sure I agree with the one night stand comments. I've had one night stands with men that I have specifically arranged to meet for sex (not a bar pick up scenario), and the vast majority of these were extremely good, most better than sex in a long term relationship. I have had the 'surprise' one night stands that just happen, and they weren't as good as those but still better than that 'expected / mundane' sex that happens in long term relationships. That said, when both partners are paying attention and there's the time long term relationship good sex is different, and better, than one nighters in my experience.
Going to the thread title 'angry about sex' though, I get angry at myself when I create an atmosphere and things get out of hand and cross the line, something happens that I wasn't expecting or wouldn't have agreed to (which sometimes leads to me getting accidentally hurt). I hate how this feels afterwards, like I've purposely recreated something bad happening to me.
