The standard for safer sex in the gay industry basically boils down to using condoms for anal sex. Since the avent of AIDS most companies have also eschewed oral cumshots (cumming in somone else's mouth) but since resseach has shown there's a very low incidence of transmission through that route, many now allow them.

While many companies do require models to certify in their release that they ae free of HIV and other sexually transmitted diseases, many gay performers are positive, they just don't talk about it.

Interestingly, I worked with one performer, Rick Randy, who has very strong feelings about how the industry deals with HIV. He believes companies should clearly ask performers their status and not pair those who are positive with those who are negative. Check out his post in the Porn section of his website.

I can't speak from a legal point of view, but ethically, I'm very comfortable producing scenes with performers without knowing the details of their sexual health. I am not coercing anyone to perform and I make sure models are using condoms. I am generally not working with models who are "virgins;" they know the score and have made choices in their personal lives. I don't work with models who are high (or at least so high they can't make good judgements) and I never induce anyone to do anything they are not comfortable with.

Well...that's my two cents worth!
