At the height of the AIDS crisis in the 1980s and '90s, fluids––blood, spit and semen––were regarded with absolute terror. Myths abounded, trickling fear into the public health sector. Governments worldwide issued safe-sex guidance, which ranged from the obvious, condoms, to the more unexpected, intercrural sex, also known as a thighjob. Blanket bans on gay and bisexual men donating blood were introduced globally. In some countries, these bans still exist.
The AIDS crisis took a personal toll, too, especially on queer and other marginalized communities at high risk of HIV infection. Lack of research and mounting death tolls caused millions of people to panic and take extra precautions to avoid transmission. Unprotected sex and kinks involving bodily fluids were deemed riskier than ever. As a result, some sexual practices more or less vanished.
Near the top of this list was the little-known art of felching, the act of ejaculating inside someone––usually anally––and then sucking the semen back out.
Felching's post-'90s renaissance
Felching's popularity steadily increased as improved HIV treatment became available.
