never done AS before, but i was doing some reading and found out that most guys get a lump behind the nipples through their teenage years and that's is gyno and it usually goes away and doesn't return. in some cases it keeps building and the breast tissue gets larger. i dont know if i am being paranoid but i did have one of these lumps behind my nipples when i was around 15 or so, it went away after awhile not too long. could i have gyno? i dont know if its fat, my nipples dont feel puffy sensitive or sore but i am afraid that i could have tissue still their from when i was younger or something?
