This is almost like a would you do gay porn situation.  Look, $5 mil for one year and lets say you DO get the butt-sex once a day.  That is roughly $13,700 a day to do something you hate for say 20 minutes.
Doesn't half the population do something they hate (work) for eight hours a day for much less than 13 grand?
Which you can then also incorporate to the original question, and just say  would you go to prison and have butt-sex ONCE for $5 mil?  I'm almost inclined to say  they can tape my ass and broadcast it on the web.
I mean, once you've done it, you've done it, no matter how much you want to cry and puke.  But what is 1 or what is 365?
Just throwing that into the convo.
