I wonder if the reason that the girls rarely say anything during the scene these days is because it’s more common for quite a few of the guys at the GH’s to be uncircumcised? Plus, even girls who are new to the business (as GH girls often are) will possibly have had multiple experiences with uncircumcised cocks (both “at work” and in their personal life).
So, it’s not something so unusual that it causes them to comment about it on camera.
This will probably be even more the case at GH’s in areas with a significant Latino population.
