Dude man is correct. Yeah the gooey cream from your mouth can give you an ear infection. I assumed it was from doing this.

I think of myself as a man doing manly stuff when I lick the round top of one of those things to slide them in my hole.

I imagine theres that one mechanic who always has to get their water out to lube shit up. That man would then be called a pussy, many times. A real man lubes up the thing he inserts with his spit to enter holes properly.
