Actually, phantom genitalia is a recorded occurrence in pre-op transgender individuals. But daaaamn OP, that is a pretty fucked up way of putting it even if you think that trans people are faking it. Calm down.
Not to mention that supernumerary phantom limbs, which usually only appear in stroke victims, are known to be induceable. It’s not much of a stretch to hypothesize that they can be induced subconsciously as well. But sure, believe all you want that only amputees get phantom limbs. You’re just contradicting both anecdotal and scientific evidence, lol.
