I don't know if men being more logically minded about sex is necessarily true. Several of the men I have dated have been far more emotional about sex than I am (I'm a woman). I actually had one tell me that he didn't want to have sex unless it was an emotional experience (I think largely because he was afraid of having sex with a woman who was untrustworthy and would use it to hurt him later), and I had to continually stop in the middle of sex to make sure he was alright cause he got so emotional (mind you, this was also the same time I was losing my virginity, I should have been the emotional one lol
). I think guys pretend not to care about a lot of things, or focus on certain other things more than females do, but I'm not sure how much of this results from social conditioning or their physical gender.
