"I was nervous when I finally made up my mind to spend the night with Nick, the sexy musician I was dating, but he was sweet, so I got over it. As we were fooling around, he seemed to be paying excessive attention to my breasts. At first, I shrugged it off because most guys have an obsession with that part of a woman's anatomy. But then he asked, `Could I play your boobs like bongos?' Sure, he was in a band, but he was a guitarist--not a drummer. I took off without looking back." --Tina, 28

"The first time I visited Seth's apartment, I couldn't help but notice all the toiletries lining his bathroom shelves. When I mentioned it to him, he confessed that he had a weakness for grooming products. It didn't seem like a big deal until I invited him to sleep over at my place--he brought a gym bag full of products. His prebed regimen took more than 20 minutes and included an almond facial scrub, obsessive tweezing, and a cucumber exfoliating peel. The next morning, he took so long getting ready in my bathroom that I was late for work. I decided this pretty boy was too into himself for me." --Moira, 30
