little lost

I've just been feeling really bad about myself here lately. I'm 16 and I've had sex with 6 different guys in 2 months. I was told by each one of them that they wouldn't leave, but half of them didn't even talk to me the next day. The last guy I was with we were pretty serious. He promised he wasn't like the other guys. He did stay around for awhile. Long enough for me to get attached and then leave. I'm honestly so done with it all. As soon as I think I've found a good guy all he wants are nudes and sex. I just feel like I'm only good for my body. I'm not looking for anyone to feel sorry for me or whatever and I don't need any hate right now. I just need to get it off my chest.
