Man, oh man. People are being rough on this thread. It's like they never seen porn before!
Anyway, your art is decent, Grim4porn, and while it's not the best, I see some potential in here. I also see you're slowly developing with your own style, and that's good! Just look at some anatomy tutorials online (Free and useful!), and try making it less porny with some drawings. If it's strictly smut, it tends to get boring, however, if that's all you want to draw - Tumblr is friendly with that stuff, so is inkbunny, FurAffinity, rule34. List is endless.
Do whatever you think is comfortable for you. Go on practicing!
