"That's an invasion of privacy, buddy." Yes. Well, no. Aside from the stupid and silly nature, this is a serious question. Let me answer my own question first to give you guys some context. When I make NSFW art (which is literally porn), even I as the creator find it hard to fap to. Now it's not because it's not erotic enough. It's just that I always look at it as a piece of work. Like, there's always a line somewhere that needs to be removed or added, or the position of something is off, or that the anatomy is just plain fucking wrong. There's always something to fix and improve on. So while I would technically say I do fap to my own art, it's just hard to (pun not intended) do so when I treat it like any other SFW art.
This is here to prove a point.

So I'm actually really curious if anyone else have the same mindset as me or that you can't/don't/whatever fap to your own work for some other reason.
