The only way to stop unsafe sex then is to debunk anal and destroy its mystique.
That's why on this Heroic Homosex site we tell the truth about anal: that it's dirty -- because there's always fecal material present in the anus and rectum; dangerous -- because of the almost innumerable STIs, more than one potentially fatal, which are transmitted anally; and demeaning -- because it turns one man into a pseudo-woman and makes his partner his oppressor.
Frot (phallus-against-phallus sex), in contrast, offers men true skin-on-skin genital-to-genital contact, free of dirt, disease, and degradation. It's far less dangerous and far more pleasurable than anal, and in time it will become the majority practice, even among so-called gay men.
Blah blah blah. Sigh. Another good idea ruined by blind radicalism.
