I interviewed adult star and director jessica drake on my Forbes blog. In her most recent movie, which is what would be considered a mainstream adult movie, she starred in a scene with three trans women. This caused something of a controversy.
"There was some discussion about not including the trans scene on the DVD, maybe just offering it online. There was also talk about putting a disclaimer before the scene, but it was imperative to me that we did neither of those things. I didn't want to warn someone how they should feel before they watched it."
