OK so since I started puberty my right breast always grew and nothing for the left..... I have been very self conscious about this and figured maybe it'll grow in due time...here I am 21 and still nothing. Idk if it could be something medical or what but it really has been getting to me lately because I'm in a relationship. We had sex a few times and he always reaches to take off my shirt to suck on my breast but I don't let him and he asked me why do I always try to hide them. I just didn't answer him. One night I let him do it and now I just can't stop thinking about if he noticed or not. I mean I no he did cause its very noticeable...I really just wanna no if something is wrong with me. Here's a picture
