This is a fun thought exercise. Your brain is choosing to interpret it as dudes with tits instead of chicks with dicks, and that's okay. It's not really wrong. A dick is kind of the core physical feature of a man.
I used to think the same as you actually, but at some point my brain decided a penis is a wrinkled recolor of a dildo. In fact in a lot of pixel/animated hentai games that have dildos/dicks, the assets are basically the same but one is flesh color and the other is RGB. So it's like if I'm okay with a woman with a strapon going to town on a woman, why wouldn't it be okay for a woman with an actual dick?
The reason is that so many "futa" art today ISN'T futa. It's shemale. No vagina anywhere to be seen and they are STILL labeling it futa. Rules 34 is especailly guitly of this. So futa art is becoming gayer and gayer. Far more masculne, far more anal, far more futa-on-male.
If it doesn't have a vagina it's not a futa. Period. No disscusion to be had on this.
Finally, the "straighest" sex is Futa/Female, and that is an objective truth.
Truth.
But no-balls, feminine futa.
NOT muslced masculine amazon with massive hairy balls.
PS: Also, an actual clit-dick. NOT a "extra" dick glued above a clit. How the fuck would that even work? Silly. Stupid.
