My boyfriend has a fat fetish. I think about it all the time.

I'm 16(M), my boyfriend (17M) is in very good shape. I am not. <br><br>After I gained a lot of weight in the past year, I felt ugly. I don't know how to explain it. I just don't feel sexy. I've always been a little insecure with my body, but I was skinny (for my height) and my boyfriend loved it. But now I'm not. <br><br>I don't feel sexy. Every time he wants to touch me, I feel gross. I feel ugly. I'm glad he is attracted to me, but I feel bad for myself because I know I'm not his "type". <br><br>Am I being selfish? I mean, I just don't feel good in my own body and I feel unsexy. But he still wants me. I know he's not lying. We have sex all the time.<br><br>It was his birthday yesterday and he was so happy when I gave him oral. I was surprised, because he doesn't like it when I give him oral, but he still liked it. <br><br>I think he wants to have sex all the time with me because he wants to make me feel good. I want to make him feel good, I just hate myself. <br><br>What the actual heck is wrong with me?
