Danbooru is not a "porn central", it's a collection of high-quality Japanese-style art. You can post explicit content, but the requirement is that it be good art, not that it get you off. And we're certainly not here to cater to your fetishes.
^ Actually, I've found several pictures that were both explicit, but that I also thought were just incredible art either way... Though I can only say that about oh, a dozen pictures I've favorited. I have 20 000+ favorites, so you get the ratio.
