The opposite really.
The whole reason I got into SFM in the first place (even started off in GMOD) was because I wanted to see more buttjobs and back then it wasn’t a very popular thing so I figured I’d do content myself with what I have. First I got into 2d then GMOD then eventually SFM and now I can make all the buttjob content I want along with all my other depraved fetishes.
