Your on a date at a fancy restaurant. You both have been drinking. He , politely, asks your leave to go to the Gents. "Piss."
When he comes back, does his hands look damp, and smell like soap? DO NOT TOUCH THEM.
Ask him, every time, "Did you soap and water wash your hands well ?" Women usually don't see how big a slob their man is in the Crapper, unless its at University dorms.
Men lie, a lot.
Would I lie to a young beautiful smart college educated fun hot woman lawyer or nurse or middle corp nanager, just to get in her pants one time?
Does she floss morning lunch and night?
