Love & Sex Answers: http://bit.ly/DanAndJenn -- Question: I'm 17 and have recently developed a crush on someone younger than me. He's about 15. It sounds really bad when I think about it but he doesn't look 14 or 15 at all. It's not a serious crush but I like him enough to want to talk to him. He seems to act like he likes me, but I don't really know if he does. Is it okay to date him even if he's that young?
