Useless

If you were to be castrated... How would you want it done.

5incher, It doesnt all go away,you still have a brain, while you cant cum you can get hard not often..Think before you do it..You wont make much testostorone so your desires will be depleated but they will be there just different..

Like many ideas the fantasy is hot. The reality is not a good idea

It depends on the person. Some guys still get partial erections for awhile.
I was pretty much impotent from other ball ******* and meds, so when my balls were cut, I lost all desire. I really don't think about sex for long periods, but sometimes see porn, or my wife naked and wish I could still fuck.

I see other guys fuck her and remember that it used to feel really good to cum.
But I'm not horny or frustrated about not being able to get it up. For most guys, it wipes out those desires.

It also make you weaker and less energy. Its a big change losing your testosterone. I guess that's why castration has been used for ages to control guys sex drive and their over all demeanor. The Japanese and the Germans would castrate prisoners of war, to control them better. They would sit the guys balls on a short post and hit them with a hammer to crush them. Painful but simple I guess. Pulping the testicles, they called it.
