I feel back pain and pain in left testis after coming across something erotica.?

seriously, I had a similar problem when I was about 20+, during sex.. Feels like somebody is squeezing your nut.. Dr. said I had an overactive nerve and suggested I sit in tub full of hot/warm water a few times a week. Really helped immediately..it totally went away in about 6 months. Another doctor said he could cut the nerve after he saw that I had good health insurance..go figure...
