Nudity double standard, what about Corey?

I don't understand. In Decoys, Corey was in a sex scene, right in the heat of everything... he is shirtless, then she takes off his pants, but leaves his underwear on. At that point, wouldn't the boxer-briefs come off?! I know they probably wouldn't want to show his frontal parts in this movie, but they could have showed his ass. I mean, you could see what it looked like through the underwear, why not just show it? If he's gonna go down to his underwear, the underwear should have come off too. I'm not saying they should have shown everything, but a quick shot of his butt would not have been too much to ask for.

He's an actor who admittedly uses his body to promote his career. They showed female butts and breast, and if any male rear was to be shown, it could have and should have been Corey’s. Whether he wanted to show it or not, the director should have made him. Part of the job. It would have made the scene much more believable.
