*lol* I hardly remember where this started either...but let´s try to backtrack...
I think what I disagreed with from the beginning was the generalization that women (more than men) needs an emotional attachment to her sexpartner. And that women in general aren´t turned on by pictures.
and I also expressed doubts concerning generalizations based on soley gender when it came to these specific questions.
That was at least what I was trying to get across. 
Wouldn´t it be ironic if we 2000 posts later would come to the conclusion that we really don´t disagree on anything at all 
I don't think we're very far apart,
in general overall.
I do think there are statements you can make regarding sexuality -- and lots of other things -- that are more true of women, and statements you can make that are more true of men. But of course that doesn't mean they apply equally to ALL women, or all men, or that gender is the ONLY factor that influences sexuality and other behavior.
I'm not absolutely sure by the picture-turn-on issue. I haven't delved into the scientific research on this. I'm mostly expressing my own opinion, and guessing based on the fact that there are lots and lots of pictures of naked women and naked men marketed to men, and relatively few pictures of naked men or naked women marketed to women. Is it because pornographers are deliberately trying to deprive women of something they would willingly buy? Maybe, but pornographers like most business people are usually happy to provide whatever they think will sell.
Meanwhile, women tend to read more romances than men do, which unlike most pictures of naked people involve an emotional element. That, and my own observations and, yes, some scientific research I've read, suggests that women are more inclined to look for an emotional connection. Again, at the risk of being repetitive but in order to be absolutely clear, this does NOT mean that no women ever has -- or wants -- sex without emotional ties, or that men don't care about emotional ties.
