Okay I'm a 15 year old athlete and I'm in really good shape. About 5'9, 135-140 lbs. I can just be sitting in class doing nothing and get these big pit stains! My girlfriend always wraps her hands around my bicep when were together and I know she can feel it but she doesn't care I guess, but it's definatlety a bit embarrassing for me. I know she doesn't care but still. I wear a lot of black or white shirts because it shows up worse on colors and when I do wear colors, I get self concious about it and put on a jacket, making it worse. So then if I have to take it off for some reason they're really bad! Nobody makes fun of me for it but I can just tell that they notice and it makes me feel uncomfortable. I do wear deodorant but I have hairy armpits, idk if the hair does it or what. I also drink a lot of water throughout the day. I think I started to realize it about 2 or 3 years ago. Should I drink less? See a doctor? Help me!!
