6 years ago,my right testil was crashed by bottle eccidantly and I had a strong ache for a few minutes.Sinces then the ache disappearded slowly during the few months,but I've had aches again sometimes.especially when I watch porno movies and when there is rains and bed weather in spring and autumn.I have no problem during sex,I'can do it 3-4 times in two hours.But I have just fear not to be a cancer.I'm occupied with sport and also have no problem during training.what can be a reason of this ache?may be producing sperm?testis is also placed a bit front then the second one.As I know if there is a tumour the ache should be permanent or in contrast,there should be no ache at all.There can pass weeks and I don't have ache,then urgently it comes (I can say that it happens mainly during porno movies or spring&autumn)
please anwser...it's very important for me
