Satisfying my curiosity is my primary motivation for my participation in Merb, so please don't reproach me for the question I am about to ask. Reading about cliff-diving doesn't mean I want to do it.
I know, as any man does, that FS without a condom is much more pleasurable than with. However, it makes, according to women who confided in me, very little difference to them. Anyway, since I don't see any other payoff for the SPs, how, if not by offering enormous sums of money, did those who did have BFS with SPs get them to allow it?
