You know what always comes to mind when I think on this (which isn't often LOL) when I was in college a guy friend of mine said that us girls would be disgusted if we knew what was going on in men's rooms...specifically in clubs. He said that I would be shocked if I knew how many men piss, handle their balls, etc. then don't wash and then come out and ask you to dance, grabbing your hand to lead you to the dance floor. Ish! That is when I decided to try not to get too worked up about germs and bodily secretions cuz there's no way to make everyone as clean as you would like them to be. I wash everytime cuz I want to, period.
By the way this might be a little gross but considering the topic...girls we shouldn't get too upset about them not washing their hands and then wrap our mouths around the same parts. Thank god my guy washes there prior to private times also, but you know damn well you've giving head to a less than sterile man sometime in your life.
Double Ish LOL.
