Yes. Phallo can be done with or without burial. Opting not to bury your t-dick does technically mean you'll have two penises.

I feel the need to point out that this will leave you with anatomy comparable to the "rabbit" vibrator, which is designed to stimulate G-spot and clitoris simultaneously. As an AMAB penis owner, if I could get an auxillary penis built to match this capability, I probably would, even if I'm dating dudes.

Edit: I've also had to come to the defense of, at measurable personal risk, individuals from the furry fandom who self-identify as hermaphrodites. "Your slur is my identity. My identity is not a slur." was the short form of the argument I made on my friends' behalf.

For neutrale individuals, I'd consider something visible like horns, but also giving them functional breasts. They might serve the "gay uncle" role in this society.

What's the difference between androgynous and neutral?
