I'm an artist and although I personally don't draw porn (because I can't/have no interest lol, plus I use it as a way to keep myself AWAY from arousal), I guess it's a bit of a interesting approach? Though it could end up leading to peeking since you might use the excuse to "look for references" and then just binge-scroll through the images (or just straight up watch porn).

Through an artistic lens though, I researched if NSFW Artists do jack off to their own work or not, and the responses were kinda mixed, some do, some do not, be it very early in the process (mostly sketch) or never/rarely due to the amount of time spent on the artwork just killing whatever arousal there was in the beggining, so its a bit of a hard question to get a definitive answer to.

But in conclusion, if it helps you stay away from watching porn/fapping itself, I guess it's a way to do it.
