I suspect that some of the women who want a quickie, really aren't getting very much from sex - even if they do orgasm. It's possible that it is far more about his pleasure and they just want to get it over and done with as quickly as possible because they find it boring.
Nope. Couldn't be more wrong when it comes to me. I know you claim only some women, but it's a pretty insulting assumption that it's inevitably the case.
When I initiate sex (and it is usually me), it's because I'm already quite horny. Even 2-3 mins of kissing, stroking, manual stimulation, and I'm probably ready to cum. Sometimes foreplay lasts longer but rarely more than 10 mins and I usually have to stop DH's dexterous efforts to move onto PIV because I prefer to defer gratification a little and cum during PIV as I find it more intense that way. Around 5 mins or less of PIV and I cum, either before or together with DH. Altogether, we're talking 10-15 mins a session.
Sometimes we go for longer, but i don't particularly enjoy it any more than a 10-15 min session. A 30-40 min session will have peaks and troughs of intensity, and I do get a little bored during the troughs and sometimes find my orgasm(s) are not as intense as they might have been. A 10-15 min session pretty much guarantees uninterrupted, intense pleasure with a very satisfying orgasm at the end.
And I think DH and I have better physical and emotional intimacy with our sessions of intense focus than if we were trying to make things last longer. We tend to be physically affectionate anyway so it's not as though sex is the only time we touch.
So yeah... fuck how you want, but most of all don't assume that everybody else's body works the same as yours.
