I've personally not used NSFW yet so I can't help you there. :/

To be fair tho, most of the time, it's not women's genitals that are painted in art. there's way more dongs "hanging out" in fine art than explicit depiction of womens genitals, which, ironically, is even more taboo than displaying erect penises everywhere. classic.
It's more the fact that a woman's entire body get sexualised too often which annoys the shit out of me.
There's plenty of male nudity in fine art.

But there's obviously a disparity, I agree with you there. honestly it's the whole "sex is taboo" or a "dirty thing" which is the most damaging in my opinion.
