recently i have had a pain that seems to be behind my testicles but still in scrotum area. It comes a little while after i ejaculate and sticks around all night but seems to be gone in morning. i have examined them a lot and there is no bumps or swelling. Nothing. Im 26 and have no history of this. I do have herpes but i feel that this pain is not related. I know what herpes symptoms feel like and this is not it. I do ejaculate more than once a day weather it be sex or masturbating. Is that to much? It dosnt hurt during and not immediatly after it comes a little later. Kind of a dull pain, not sharp. It kind of freaks me out. Please help!!!
