Dear god, I feel like I need to shout this from the rooftops because every time I mention it in passing, it feels like someone's jaw drops in astonishment:
YOU CAN HAVE BOTH A PENIS AND A VAGINA! IT'S CALLED A PENIS-PRESERVING VAGINOPLASTY (if you're AMAB) OR A VAGINA-PRESERVING PHALLOPLASTY/METOIDIOPLASTY (if you're AFAB)!
YOU CAN HAVE BOTH! YOU'RE ALLOWED TO HAVE BOTH!
