Well I don't think its Gyno, there is no hard or even lumpy tissue. And when my nipples are hard, they look great, and it makes the chest closest to the nipple go flat as well instead of its little "cone" shape that flows into the puffy nipple. Know what I mean there.. the large puffy nipples make the skin around them cone out.. but when the nips are hard my chest looks awsome. And I don't know what I can do to make it stay that way.
