"Come inside. It's fun inside."

You ask her out. She says yes. Ta-da. She's your girlfriend

If you're the age to really believe that's how it works, you're too young to use a condom for its intended purpose.

She's a girl, and she's your friend, duh!
P.S. That quote always sounded a bit dirty, to me.

I know right. Never knew I'd have the perfect chance to use it until I found this!
