How Do You Unlock Your Door?

One night this guy and his girlfriend are about to go into his apartment. Before he can open his door his girlfriend says, "Wait a minute. I think I can tell how a man makes love by how he unlocks his door."

"Give me some examples," the guy replies.

"Well, if a guy shoves his key in the lock, and opens the door hard, then that means he's a rough lover and that isn't for me. If a man fumbles around and can't seem to find the hole than that means he's inexperienced and that isn't for me either."

Then she says, coyly, "Honey, how do you unlock your door?"

"Well, first before I do anything else, I lick the lock."
