My wife was angry. She said: "It's unfair! A guy can screw a different girl every week and he's considered a stud. But if a girl screws even two guys in a year she's called a slut."
So I man-splained it to her: "Think of it this way. If a key opens lots of locks it's a master key. But if a lock is opened by lots of keys... well... it's a shitty lock."
My wife bought one of those do-it-yourself waxing kits. Really wanting to please me, she asked with a wink: "Should I do the sides and leave a little strip down the middle?"
I told her: "I'd prefer you have no moustache at all."
