I make horny art. I want to post the horny art here, however some of it is on pixiv (censored) and some of it is original and I haven't posted it. Is it okay/desired to upload directly to r34?

It's ok to upload nsfw of your original characters on here

Ah, I must have phrased that wrong.

If we make nsfw that we haven't posted to other sites, can it just go on here? I know theres a source bit in the description, and r34 is described as an archive, so I was unsure of if we can just... upload stuff just for here. I do NOT want to upload to DA and my alternatives are... dwindling.

You should be uploading it somewhere else first and provide accurate sources. Other than that, it's allowed.
