Lump in testicle/discomfort
I noticed a lump in my right testicle about 5 years ago. Last year, I got it checked out but the doctor said it was nothing and that it was just some kiss or cyste or something. The thing is, whenever I have sex and get really arroused, my right testicle swells to twice the size of my left one and the lump gets bigger each time and when I have sex for a long time without ejaculating and get what mose refer to as "blue balls" the right one is so sensitive and when I do ejaculate there's something really discomforting and my right leg starts feeling a little numb. I have no idea what could cause this. Any ideas?
