Your signifanct other is a 10 but you're just a..

Alright I wanna see if I'm the only one who feels this way. I've been dating my boyfriend for a while and when people see us together they're surprised. Why? Because he's hot! He has the fit body and the nice face and he's everything you could possibly want in a man. So when they see him with a girl like me who's not the skinniest and not exactly a 10 they act like its a joke. Do any of you guys ever feel insecure because you feel you're not in the same league as your significant other ?
