Why are my nipples always hard?
Okay, so I am a 17 year old girl and I don't really have anyone to talk to this kind of stuff about but it seems like my nipples are always hard. Like at practice, which is with all girls and trust me I like guys, the other girls will just be wearing a sports bra on top but I always have to wear a bra underneath otherwise my nipples will show. And i guess i get cold a lot but at practice I am not and I'm definitely not during a practice outside in 90 degree weather! I don't understand! please help! thank you:)
