Hi! I just started making SFM porn, however, I am not sure how to add my own name to the "artist" tag as I made my porn, however, I'm just clueless how to tag it as I made it, thank you!

Warning: SFM models are harder to meet quality standards with. You may want to make a personal gallery at some other site for now.

This is why I mentioned to read all in the guidelines, because every single time someone has asked if something is fine to post verbally only, it usually ends up getting deleted for being ms paint doodle.

Yeah, this isn't exactly site to post your first SFM porn projects and with 3D artwork if readily available models are used, we judge them by other aspects what have been done with the assets, including posing, framing, render, etc.

As for creating your own personal gallery where nobody but you will curate content, there are a lot of choises: https://e621.net/wiki/show/howto:sites_and_sources#table
With pornographic SFM content, there's furaffinity, furry network, sofurry and weasyl if it's furry/anthro related and patreon, tumblr or twitter for any kind of content.
