Have you ever been caught masturbating?
Once - like a long long long time ago.
Never since then - which is somewhat surprising considering how much I get myself off. It's not like I need toys or anything - just a minute or two alone and I'm done.
I actually do not think I ever have been ~YET anyway... (or not to my knowledge), although I certainly would not mind getting caught by a certain someone and depending on the situation. I take it that you do not mean caught 'on purpose'?
Now have I caught others? Yes.
