I am a fifty-three year old male. For about the last two weeks I have experienced a minor pain in my right testicle when I orgasm. The pain is only at the time of ejectulation and is only for a couple of seconds. I have no pain before orgasm or after and it is not severe enough to stop having sex. I can not feel out of the ordinary, it is not painful to the touch and I feel no discomfort going to the bathroom. Any ideas of what this might be and what should be done about it?
