Wax

"People seem to think to "wax" something or to "wax" someone is strictly to fuck or bust a nut. "Wax" also means for a male to perform fellatio on a female."

You cannot perform fellatio on a female. The correct word for performing oral sex on a female is cunnilingus. Whether performed by a male or female is irrelevant.

You can only perform fellatio on a man.
My girlfriend and I did a 69 last night. She performed fellatio on me while I was performing cunnilingus on her.
