Only ever heard of one.. my supervisor apparently was in a relationship with one for a couple of years.. it had been a year since he'd broken up with her and only had just then started to think about sex.
He used to HAVE to give it 2-3 times a night 7 days a week.. bugger that.. urgh..
2-3 times a night would be good for me.. but NOT 7 days a week.. lol
