I wouldn't consider that a guy. If it's a futa, it isn't a dude. Nor your vagentlemen either.
Imagine this; you take a bite of an apple; It is crisp, juicy, delicious and nauseating. You immediately realize that the reason for that last taste is because it has a worm in it, and everywhere the worm touched has rotted. Perhaps you're the sort of person who either already enjoys the complex melange of flavors that worm and rotting apple represent, or perhaps you can simply learn to enjoy it. Maybe you're the sort of person who could ignore or avoid the contaminated parts and still be able to enjoy the rest. If it was me, after I finished retching, I would throw the apple away.
This is almost exactly the same, except that a worm would eat randomly, whereas in porn either it's the most important bits that are replaced, or (in the case of traps) literally everything else. Regardless, my interest in eating an apple would die as soon as I became aware of the infestation, and this is no different.
