I've made a Weasyl account specifically for mature artwork, which you can find here:
https://www.weasyl.com/~yiffylumi

You may also follow on Twitter: https://www.twitter.com/yiffylumi
Or on Tumblr: http://yiffylumi.tumblr.com

Of course, you may always follow my clean art on Twitter, Tumblr, and Facebook:

Please note that I have no intention of opening a mature account on FurAffinity at this time.
