I probably wouldn't take a blowjob from a complete stranger if she approached me out of the blue just for that reason. Don't wanna get HongKong Dong.

In fact I have turned a woman down... at a pool hall... much to my friends' bewilderment.
But if I met her and we hung out a while and she was really sexy, not whorey, my sensibilities would probably crumble and I would accept it.
