Yeah I thought about this before, this might sound too deep or crazy but it make sense to me. When male actors are fully naked, they are serving as a tool, they mean nothing but a representitive of dick to the sex scene to fuck the female actors. Honestly, they could be replaced with a dildo and the scene will remain the same. In other way, the director are dragging the male out of the porn so people could focus on the female acter.
However, when males are dressed with socks or shirts no matter intentonal or by accident, they become a part of the sex scene, they will be receiving the same attention as the female actors are. That's why I sometime really enjoy straight porn as a gay man,
