That's something that can be referred to as "agender dysphoria", and it's pretty uncommon, but not unheard of. If your discomfort with your genitals is severe, surgery may or may not be an option. Frankly, I know very little about genital nullification and whether or not it can be legally done. If surgery were an option you'd be interested in pursuing, you'd have to find a doctor willing to perform the surgery and who can give you information on it. Most likely, you would also need a therapist to diagnose you with gender dysphoria.
Know how you feel, I want nothing there too. From what little research I have done, your genitals are where your body's sex hormones are stored, so you'd have to take hormones from then on to prevent osteoporosis or other stuff like that. But I'm not a doctor. also, the surgery for that is called an emasculation, if you want to do research.
This has probably crossed your mind before and shouldn't hold you back if you really want to transition. It will probably be infinitely harder to find a partner who is ok with nothing being down there. I don't want to be a spoilsport and discourage you but you should probably be aware of the negative consequences such a decision could entail.
Well, the idea would be to solely remove the testicles, and keep the penis. And IF I was still unsatisfied with that, I could then take further action from there. But yes...it would potentially jeopardize the notion of having a partner...and would require a very open minded one (I've had trouble enough getting girls as it is...-_-) But...then again, with a neutralized sex drive, perhaps I wouldn't really need a girl.
Your hormone levels should be checked. They play a big part in our sexual identities and sexual appetites.
