Does any one else feel the same way?

Okay I'll start out by saying that I have no figure. I'm an A cup and 110 pounds. I've been dating my boyfriend for over four months now, we're both young, still in highschool. Sometimes all I want to do is please him, turn him on and feel sexy. But I can't hardly do that because I'm so not curvy. Today he asked me if he could watch lingerie football. I wasn't paying attention whenever he asked me so I just said "sure go for it" but now that I think about it, I don't want him to watch it at all. I appreciate that he asks me though. I don't want him to read playboy or even look at girls with big boobs. But of course, I sound controlling and I don't want to tell him and have him whipped. That's not my intentions. I get jealous of those girls with the fabulous bodies. It just seems like he wants what he doesn't have, a girl with a nice body that he can fondle and drool over. I I get jealous anytime he mentions curvy girls. He tells me I'm beautiful but I doubt it sometimes. I just really wish I had a better body. To make him happy(-er)
