I can't see this video and I don't know the specifics of its claims,
but,
Once I did hear some experts discussing this in medical terms and there really were some kinds of diseases and conditions common to the homosexuals that involves feces and ingestion of feces,
and
something to do with feces inside the penis. If it takes you a number of times to figure that one out - same here.
There is also something called (or was called) Gay Bowel Syndrome which had something to do with semen being places it ought not.

Sorry for the disturbing topic but I'm just passing on what was on this radio program and seemed to be a very scholarly non-political conversation among medical types.

It's called safe sex. Most responsible gay men wear a condom when going anal. It's no different from getting a disease from banging a girl in either of her holes without a condom.

STD's are not exclusive to gays.

And the term Gay Bowel Syndrome is indeed dated. The Canadian Association of Gastroenterologists withdrew the term in 2004 because the condition was not gay-specific and was coined pre HIV era.

This.

yeah, he came onto me in pm.

I'm going to set up an anti-hetero propaganda meeting and use videos of Japanese vomit porn as my "research".
