>>99017051Well I'm not about to share anything, but what
>>99017156 said holds true for me, too. The sketch part is when it's the most titillating. It's when what I specifically REEEEALLY wanna fap to starts taking shape. All those parts of the body you like seeing, the pose you were wanting, the act you were so, so much in the mood for begins to come into focus. Don't have to go too much further than that.
Admittedly, if I'm drawing something just to fap to it, I don't typically finish it (or ever post it online). I might go back later and clean it up, add color and whatnot, but it never resembles a "finished" piece. Even then, when I just do a finished sexy picture because I want to, I can find myself slipping a hand down my pants from time to time. I simply drew what I like, after all. I just wasn't in the mood at the moment- but coming back to it later, when my eyes haven't been staring at it for hours, I'll feel different and appreciate it more.
I do find it odd though that a lot of people say that it's the errors in the pictures that bug them. If there are errors, I just fix them. If I see them, someone else probably does too. The glory of digital art is that you can make changes. Fix that shit and enjoy your boner.
