When I was young I have 2 friends one with both pus*y and di*k. Another one has huge huge natural clitoris which I found out unintentionally.What little experience I have with trans women included one pool party where one wore a bikini top but board-shorts. And everyone was like: "Cool, you do you". That said, I tend to hang around a pretty inclusive bodypos community.
And even then, being a biochemist, I have enough understanding to appreciate that gender isn't even strictly binary from a DNA perspective anyway. It's entirely possible Sukkhon could be XX, so genetically female, but for some reason the DNA switching during meiosis gave her the SRY gene on an X chromosome which regulates testosterone to give her her dick.
Hell, from what I've been taught at college, with phalloplasty, it could even be possible while technically unethical to surgically modify someone to be a futanari, with both a dick and a pussy. Just modify the clit to be bigger.
