Sex, Deaf But Not Dumb

This joke is R-rated.

Two deaf people get married and during the first week of marriage they
find that they are unable to communicate in the bedroom with the
lights out since they can't see each other signing, or lips to lip-read.

After several nights of fumbling around and many misunderstandings,
the wife figures out a solution. She writes, "Honey, why don't we
agree on some simple signals? For instance, at night, if you want to
have sex with me, reach over and squeeze my left breast one time. If
you don't want to have sex, reach over and squeeze my right breast two
times."

The husband thinks this is a great idea. He writes back to his wife if
she wants to have sex with him, reach over and pull on his penis one
time. If she doesn't want to have sex, pull on his penis two hundred
and fifty times.
