I'm getting sick of waiting.

I've never had a boyfriend and it's what I really want right now. I'm almost 17 and overweight. I think my weight is the problem. I have guys asking me for sex and chatting me up etc ( Ive turned down the guys who want sex ) but no one has asked me out or even like full on wanted to be in a relationship.  Is there something wrong with me? I'll attach a photo of me. All I want is to be loved.
