If youre stimfapping and watching another man have sex thats kind of weird. Are you gay? Men are ugly and gross and youre watching one have sex? Kinda weird

Lesbian sex is tolerable but their incompatible genitals facilitate suboptimal sex.

So to sustain optimal stimulation of genitals a female requires a penis. Which is futa. Futa is not trans/shemale/etc, it is a true female with a penis. Futa porn is animated, futa is fiction, if it isnt youre either watching a man have sex or a woman with a prosthetic.

Due to the absence of observable men your brain unconsciously comprehends the futas penis as your own so your immersion is enhanced. Rather than unconscious competition with a male whose penis is likely larger than yours.

If youre a woman you can observe sex without ugly yucky men in it
