I had a 10 year relationship in which my sex life was good. My partner seemed to enjoy herself and always said that she came. Yet my inquirey in hindsite was an invitation to be lied to. It's not like I could tell if she was cumming or not. That in itself is a sign that maybe she didn't get off. Sometimes she did initiate sex so she might have enjoyed me. I always orally pleasured her as well.
There was another woman who enjoyed me. At least she had the honest to tell me whether she came or not. She always came from being in the top position.
I learned in later years not to ask the woman if she got off or not; that it put pressure on her, reducing her odds of climaxing. Not only that but questions as to whether I'm good in bed or not are totally useless. It's not like men or women will tell their partner that they "suck" in bed (no pun inteneded...really).
Now all of the other women I dated just seemed to be going through the motions sexually. I'm 7.5 inches long with average width. I guess that size isn't the issue. It's attraction. I'm an average looking guy. I heard that something like 75% of women don't cum until their 30s...or maybe it's 25%. I can't remember.
The fact that men will pay for sex and women won't is a clue that men enjoy sex a lot more than women do. Then again, it's supply and demand. Men have to do the pursuring. Nevertheless it's evidence that women aren't that sexual unless they are attracted to the man they're sleeping with as well as comfortable.
I figure this post is a waste of time. That the women who really enjoy sex will post and the other women who do not won't--in fear of seeming asexual.
