A deaf couple were honeymooning in Hawaii. Having lived sheltered lives, they 
were very nervous about their sex life, and communicating their desires to one 
another in a darkened bedroom. The husband asked the wife in sign language 
"Honey how should I tell you when I want to have sex?".

The wife replied in sign language, "if you want have sex nibble my right nipple 
once, if you don't want to have sex nibble my left nipple twice".

With the ice broken, the wife asked the same question to the husband.

He replied "darling, if you want to have sex pull my penis once, if you don't 
want to have sex pull my penis 27 times".
