stretch marks

hi everyone...❤️ I'm in high school right now & I am just very very self con joys about my stretch marks. I know that everybody says that you should love your body and everything but I have what feels like stretch marks all over my body. they're on my lower back, my thighs, around my hips, my boobs & I just don't know what to do about it. I'm embarrassed to wear a swimsuit and I'm not even too overweight, I just have huge boobs and I'm what I'd call a "solid girl." my boyfriend and I have been dating for a while and he's touched me but never seen me naked & I am so scared he will run when he sees me. somebody please help😭
