The acceptance of transsexual content was discussed years ago with the decision being to allow it, since it has a long history of being included with “straight” porn not “gay” porn. It’s not compulsory to watch it.
It is tagged as “Trans” and has the word “trans” in the discussion title so it’s easy to avoid.
I should also point out that it’s been scientifically proven that posting a reply in a discussion tagged as “Trans” will make you 10% more gay unless you are wearing the Crown of Masculinity like I have on my avatar. Gay people will, of course, become 10% less gay.
