I would urge you to save your money for a trip to see the urologist in Michigan who is doing elective orchiectomies. His name is Dr. Marc Arnkoff.

I went through this "phase" in the mid-1990's, so I definitely understand. I wanted the testicles gone ASAP. I bought a burdizzo from a local farm ...

I was castrated in 2000. I have been on estrogen for years. I still very much have a sex drive and I still get semi-hard erections. And I am in my 40's. YMMV, indeed.
