Kevorkian Logic

I was talking to my friend and he posed an interesting question.

Your stuck forever on a desert island and, to keep you company, you can have either:

a) The greatest conversationalist ever, but who is unable to have sex
or
b) A mute who is a sex-beast.

They both look the same.
Who would you choose???
