Here's the thing - lots of impressionable gays in sexually formative states simply do not equate porn as fantasy. They think, Oh I should try that. Or, Oh that looks hot let's do it. Meanwhile, does the porn include a message - after the top cums inside the bottom's ass and the jizz is splooging out as they screw - indicating that you should never do this with a stranger or with someone of whose HIV/STD status you are unaware? Do they include messages about hepatitis? Do they attest to the safety of the models/actor participating?
Yes, porn is entertainment. Not education. It's meant to arouse and fulfill a fantasy element. But in some ways, it is sex ed for a lot of gays, who aren't getting that information at home, school or from friends.
So I have mixed feelings on the whole thing. I don't mind bareback porn, but then I am sexually educated and am not going to stick my bare dick in any random ass. The 17 year old with a thing for muscle daddies watching bareback on itsallgay or xtube might not be so wise. And I don't know about anyone else, but I worry about that 17 year old. I want him to have good LGBTQ examples and grow up healthy, well-adjusted, productive, etc.
