Yeah, I've noticed that with the new Pose. The Cock goes into your partners thigh. LOL. It has to go somewhere. Remember, this is a pose took from the M-F pose so adding a cock, it's going to happen. I think other than that, the pose has been done very well. I like it a lot, although I haven't really tried it yet with one of my few Male friends.
But, it's a new Pose and I think only you and I have noticed it.
As of the other poses I haven't really noticed this intersecting. Too busy with the action to take notice.
If it does happen, then I suppose it's what angle the camera is, yes? Nothing is perfect. I bet there are little "errors" in the other orientations as well. But, of course that is just a guess.
