I love This American Life!! And I totally back that up – I had one week of mysterious, raging testosterone, and was visualizing very graphic things about everyone from the ugly librarian to hippy check out gal…it was literally compulsive, some of the images were even like, “Ahhh! No! Can’t..stop…ewwwww”. So – I empathize. Furthermore, I happen to think sexy women are very sexy (ha!) and I look too. I think it’s fine as long as you’re a) not inappropriately drooling, which is just kind of meat-head, and b) paying sufficient attention to the lady you’re with. That’s all the women are worried about anyway.
