Who cares what others think? In all likelihood they masturbate themselves but toe the party line when discussing it. If they say they don't, I (me, not you) would call them a liar or a freak of nature.

Masturbation is natural. They have documented fetuses doing it in the womb.

Don't even get me started on religions and church.

I have been masturbating for close to fifty years. My girlfriend and I sometimes masturbate together.
