Wellll... you have to recognize that some of the crowd that hates condom porn are people who are living with HIV. They're watching porn to escape, and they don't want to be reminded of their situation. I've heard that commentary from several people.

However... I also think that the same thing can apply to the scenario you just described, for example, if you have a website marketed as "all twinks" or something like that, and you throw in a scene of two 20 year old guys and a 40 or 50 year old guy joins in, a lot of the members may get grossed out by that.

Likewise, you have a scene between two hot hairy guys in their 30s or 40s and stick some pale, skinny, hairless 18 year old twink in there, and I'm sure you'll get howls of disgust from at least some of the viewers.
