It's an odd thing. I was with this little Peruvian cutie and she got carried away and bit my nipple. It didn't draw blood but it was a damn good pinch. I'm on test E with liquidex. That nipple now has a lump underneath almost as if I'm getting gyno or something. Maybe it will go down in due time (it's been one week) but it's a concern. Would you check with a doc or should I just chill?
