Castrated human, neutered human, eunuch, gelded man
I was snipped at age 40 and it was something I had wanted all my life (since childhood). Wish it had been done sooner as it improved my quality of life immediatly. I really didn't want balls (or pubic hair). I really had no desire to transition or anything, just wanted my nuts gone.

Everyone reacts to castration differently and I cannot give advice to you about it. Just know that it should never be done unless a doctor is doing it and it is something you want. Read a lot and speak with anyone you can, who has been castrated before you make the trip.

Physical changes for me included the loss of body hair, weight gain and loss of a bunch of libido. People talk about "the eunuch calm" but I have not experienced it nor has anyone who has upset me. I am bi but because of castration there really isn't much I can do for a female (traditionally that is) so I am submissive with men and am happy to be with them. Yes, I can have orgasm but it takes some doing.

No, I don't get erect anymore and no matter how hard you might try, it won't. My penis is just a soft useless noodle for urination now (but I've been told it looks cute). Yes I do take testosterone for bones but it doesn't help much in other ways.
