this blogpost, I defend safe sex:
Most adults have sexual fantasies; this should be defended. (When we hear people attack other's sexual fantasies as 'disgusting' freedom-loving people should be Minute Men.) Social research has demonstrated that most adolescents and adults masturbate at least once each year. Sexual fantasizing is highly diverse: What one person considers exciting might be boring or scandalous to someone else. Outside the female vagina, male ejaculate can have little physical effect--though people fetishize it, probably in response to cultural taboos. One male describes a sexual turn-on involving the licking of his own ejaculate, a harmless (if quizzical) practice, and a local publication discusses it. So what?
