Sex plus insomnia equals Nymphomania.....

Is this true?

I was talking to someone the other evening and at about 8:30pm, I said I needed to get off the phone and start getting ready for bed because if I didn't I wouldn't be able to sleep all night on account of being an insomniac.

He got all excited! I wondered out loud what the excitement was about and he told me you know, insomnia is related to Nymphomania, well maybe not so much Nymphomania but a very high sex drive. Hmm, very interesting! Could there be some truth to this?
