But of course, the claim that 'men think only of sex' or 'think of sex at least once every 3 minutes') is just another Urban Legend. Not based on any good research, and most men can tell you that it is nonsense too (not that you have to believe them, but hey).
In fact, SL Gor kind of 'proves' the lie of it. Why do you think the guys in SL burn out so quickly?
My claim: Men think about Sex LESS than women do.
