Most of my fantasies are about becoming / being a complete woman, although after I climax, I literally feel like I want to just be a guy again and live my life.

So, even if we had the technology for perfect, painless, and free (but irreversible for this argument) "sex reassignment"...it still wouldn't even make sense unless you're basically always horny. Which isn't a good way to go through life anyway, so even then that should probably be addressed first, instead of just becoming your fetish.

Considering we are (thankfully) very far from 'perfect, painless, and free' transitions...yeah, stop chopping off your bits, you retards. Aside from hurting society, you're only hurting yourselves.
