I had mine over 10 years ago. I can still get erections (especially if I'm on T) and can still orgasm the same as before. I made the unforunate mistake of NOT being on any hormones after I de-transitioned about 8 years ago and have since probably caused quite a bit of harm to my body. I didn't do anything about it sooner because I had falsely believed the only side effect of not having hormones after an orchi would be lack of energy (and I've always had PLENTY of energy).
My biggest suggestion to anyone planning it is, sperm storage. Yes, yes, I know you will tell me and everyone else that you won't need it, that you are a woman, that you will NEVER seek to impregnate anyone. I said the same myself, but you owe it to yourself to save some of your seed should you ever desire a child for any reason - especially if you end up with another woman as your partner. Worst case scenario, you make a donation, and never use it - whoop-tee-doo!
Second suggestion is don't stop taking your Estrogen, Testosterone supplements, etc unless you'd like to kill your energy levels, break down your bones faster, and gain a lot more weight.
