I may tolerate the presence of a single futa character so long as scenes with them are avoidable. But that's as far as my tolerance in porn goes. The only penises I want to see in porn are those that I can identify with.
If it's a futa girl having fun with a girl, I can try. Of course, provided that the penis is normal size, and not the size of a man's thigh. And, of course, with a nice visual.
So assuming Male MC, I perfer normal women. But futa's not an immediate no, having said that I won't do anything with an all futa game, I want multiple LIs in my futa games with some of them being normal women.
I like Futa
I like when it's the Futa that dominates
Love Futa on Female but when it Futa on Male then it only needs to be femboy because otherwise it's a turn off
