I keep reading the title of this thread as 'God excuse for refusing sex'

I have now reached the age where I prefer the 'Viva exam' to the practical, but recently had the unnerving experience of being told when I reminisced happily about the previous night's frolics. "Good I'm glad you enjoyed it, I was so pissed I can't remember much of it"
There was I with egg on my face, and a stiff neck!
