Ok, I'm sure this'll bother some people, but I felt coming here was the most intelligent thing as it'd be the best place to get informed answers that I can share with others.
Long and short (pun not intended), while I am a happy male, I'm not attached to my penis. I've thought about two mods, streamlining (moving the testes internal, removing one if necessary, dunno ifn there's room) or perhaps on the more extreme side, replacing it with a vagina. That last one was inspired by a few bits of art here and there of characters like that, and one photo I have of someone that claims to have been born straddling genders, and lately by a video of Buck Angel. Right now its a casual thought, I've not the knowledge necessary to make an informed decision, so I've come here for that and opinions. Obviously this is possible, its merely a matter of a partial gender transformation (correction?), but the fine details are important, then there's cost, and safety. Also whether its even possible to find someone to do work like this, unlike many body mods, self surgery or amateur surgery isn't a wise idea. Largest question is what to do with the testes, remove them, or since I'm not looking to change genders, should they be internalized? Testosterone production would continue ifn I understand it right, which would take care of potential hormone issues, but will it bring any risks.
Thank you for your answers and help in this issue, what I learn here I'll save it, and post it as a follow up to my comments about my interest here, and what direction I choose to move in.
