My left testicle rides up above my penis during intercourse (which causes lack of ejaculation)

I am I 40 yr old male. I had a hydrocele surgery 5-7 years ago. I also had a partial vasectomy done when I was in my early twenties. The reasons I am posting are, 1) My left testical rides up above my penis during sexual intercourse, ( which causes lack of ejaculation on my part), 2) recently my urine stream is not as strong as it once was, 3) after urinating ( not all the time) I feel I still have to urinate some more, frequently enough after standing for a min. there is semen like substance relieved, 4) as if all this isn't enough I have started having testicular pain on my left side which is the same side I had the hydrocele surgery. IS there any idea as to what my issues my be caused by? I am planning on going to the dr in a couple of weeks, I am just trying to get an idea as to what is going on with my body. Thanks for your time and any answers will be greatly appreciated. J.D.HURST
