I don't know. I thought it was pretty common for some women to get moist over a man who cries. Maybe the actual tears aren't triggering wet panties, but something is. Some just love emotional men. And regarding rape jokes - the world would be a better place with more of them. More rape jokes, not rapes.
Semi related, it's said that a baby's cries instantaneously lowers a woman's sex drive, or in my sick head, dries them out faster than The Flash at full speed, so even though this thread is likely some joke I've missed, I can believe it.
Basically, the key to holding a woman's sex drive is to be Channing Tatum, as long your job is secured and you can satisfy her non-sexual needs, be they in the form of jewelry or chivalry, or both.
