Testicular Pain/ Scrotal Pain

[cg21]

I am a normal healthy 23 yo male. About 3 weeks ago after having normal sex with my g/f I noticed very uncomfortable pain in my right testicle and my upper inner thigh and hip. I went to see my doctor and he examined me and peformed all tests necessary to ensure nothing serious. Nothing serious came up and he thought that it may be a muscular/skeletal problem. This problem only occurs about 10 minutes after sex and lasts for about 30-60min after. It occurs on cue within this time frame every time. The pain is not necessarily in my testicle but i can feel it in the tubes right below it and by the base of my penis and down my leg. During the day I am fine, my testicles dont hurt - i have a little nagging pain in my back but nothing serious. This condition only happens after sex like i said and it is like a pulling sensation. When I first experienced it the pain was so severe like someone put on a boot and kicked me in the testicle but since then its gotten a little better but not too much. Its been 3 weeks now and I was wondering if anyone else has experienced symptoms like these? Any help would be really appreciated since i cant find anything on this anywhere else.

one thing i forgot to add to the situation.....it really only affects my testicles when standing, if im laying or sitting when the sensation comes on i just feel it in my lower abdomen and leg, if anyone has any advice please let me know
