How to keep everything working as a non-op MtF?

[svartekaptenen]

Well as I am dating a transwoman now I can tell you this:
Your testicles will shrink as you consume the hormones, however
my girlfriend can still get a hardon and can still climax and she has
been on hormones quite a while so she has breasts and somewhat
wide hips.
I will ask her some questions when I meet her tomorrow and perhaps
I can give some more information.
