They tell me I’m beautiful?

My friends, my family they all tell me I’m beautiful. I believe that’s it’s true. I’ve also been told that if I would just loose weight “I could have anyone I wanted”. It doesn’t feel good to hear yet, I’m sure there is truth to it, & I’m in the thralls of trying to get that goal I’m down 16 pounds. But my whole life I’ve been who the guys want to sleep with (which I will not do it gives me nothing), or I can just tell they are attracted to me, my looks & my personality whatever it may be… but I am NEVER EVER approached or chased. My friends just say I’m a really strong personality with black cat energy. I’m not 300 pounds or something like that. Just how do I move from the girl who’s chill because she has 5 brothers to the girl who’s worth dating. Even if I try to be friendly with a guy they assume that I like them. Even my younger brothers friends have asked “does your sister like me?” And they always have to tell them no she just that nice. I want to have friends who are guys etc. but it’s never a thing for me.. what is this? How do I change it?
