Fair point, except I don't know when it's gonna show up, and Futa just... kinda kills my boner about 98% of the time, and then I have to invest more time (and probably a lot more repetitive movements with my appendage) to get the engine up and running again.
There's the rare Futa-containing work of art that doesn't have that effect, but those are sadly few and far between. I avoid Futa content where possible the same way you'd probably avoid necrophilia and scat (yeah I know, it's gross to me too) even though it... apparently turns some people on?
I dunno. Fetishes are weird.
