Off topic, but what is the appeal of futa to straight man? is he so straight that he can't even look at a naked man but want to see straight porn so he just watch futa? or is he a homosexual/bisexual in denial? because you know, isn't gay if looks like a woman!
Because Futa is technically not gay
A lot of men don't like looking at other men in porn.
Could be for any reason.
- Guy doesn't want to see another dude's balls.
-Guy can't concentrate because the cameraman is up the man's asshole.
-Guy can't self insert
- Guy is jealous or envious of other men.
Futa solves this problem simply by making the other "man" a biological woman with a magical penis. The "penis" could be an elongated clit or summoned from vagina space or surgically attached and so on and so on, but keyword, biological and at the end of the story they're still a woman- Nothing will ever change that fact.
Side note: this works for lesbian / bisexual leaning women as well.
They don't want to watch a man fuck a woman, but at the same time, they don't desire lesbian sex because that's gay. Presto! Futa porn to the rescue! Two women, loving each other in the heterosexual way!
Now this is where semantics kicks in.
Older Futa works, the woman didn't have balls.
New Futa and Furry works, the women have MASSIVE HUGE BALLS.
In my opinion, this is where the line is drawn. Balls are purely mascaline features. To have balls is to be a man and no "It's only gay if balls touch" isn't a slogan to live by.
If it's a biological male, it will always be gay.
Trannies are offended by Futa because Futas at the end of the day, are still biological women with a functional penis, no balls in 99% of Futa Media and a functioning uterus, the ability to have children. Trannies are mad because no matter what, it's the dream that will never happen.
TL;DR it's all about avoiding those labels of being gay or bisexual and REEEEEing at imaginary women having more than they ever could.
These faggots would rather cut their dicks off or pretend to be women than admit they're gay or bisexual.
