Some do yea.
I've seen a few do it.
I tried but it doesn't work. I even tried the clothes pins on the nipples thing but I barely feel even that. Some guys are sensitive though.
the wording of this and your use of the word "also" leads me to believe that you do this as well…that being said…i am WAY too distracted with that visual to answer this question ;-)
I'm sorry did you say something?? :P
ha! that will BARELY scratch the surface! ;-)
No, maybe my testicles
I have very sensitive nipples....so yes.
Curious are we?
