Hello, I had puffy nipples for atleast 5 years, I m 15% body fat, my nipples are only puffy, no hard lump, my chest is fine because I train it but the nipples are pointy, (when I go In shower or I touch them abit they shrink at a perfect size). I do masturbate a lot and I read that high prolactin can cause puffy nipples, is this why I have puffy nipples ?
