From what I have experienced myself here on Newgrounds when posting artwork (especially nsfw) and from what I have gathered by talking to other NG users, it seems like the "art portal" is for pussies and boobs only.
It makes me want to delete all my artwork here that doesn't show a naked female character; which is, like, everything.

Naw there's dicks and spread open assholes too.I'm pretty sure there is people that don't want to see Marvin's stuffed butt in the portal but then again why are they even clicking on it when they see the A rating on it.

I agree, some people are just ignorant. Although I'm pretty sure that male characters have a disadvantage here when it comes to p0rnart no matter what.
