I most certainly do enjoy it. Mine get pretty erect and stimulating them sends signals to my cock as it grows as well.
Ever since I started teasing my nipples during pleasure, I can't seem to masturbate now without doing it. It just adds more to the overall experience and makes my orgasms so much more explosive.
My cock head and nips seem to be related. I can get rock hard from pleasuring my nipples. Mmmmmm I love to masturbate
