Many transwomen are stuck with balls only because healthcareplz not by choice.
Testicles and penises are different things, many are okay with having dick, but very rarely with balls.

Please just avoid talking about girl balls at all, even ironically it comes off as fake woke and fetishistic.

I do not much recommend Suzan's place, but it is not without reason that these wiki pages:
https://www.susans.org/wiki/Orchiectomy and https://www.susans.org/wiki/Self-mutilation
contain not only warnings against auto-orchiectomy but also graphic descriptions of what happens afterwards.
