I can tell how a man makes love.

John and Jill were about to go into his apartment, and before he could open his door, Jill said, "Wait a minute, I can tell how a man makes love by how he unlocks his door."

John says, "Well, give me some examples."

Jill proceeds to tell him, "Well, the first way is, if a guy shoves his key into the lock, and opens the door hard, then that means he is a rough lover and that isn't for me."

"The second way is if a man fumbles around and can't seem to find the hole, then that means he is inexperienced and that isn't for me either."

Then Jill said, "Honey, how do you unlock your door?"
