Hi, I am a 23 year old male and I have been looking through old posts but still had some questions about my testicle's size. The left one is at least twice as big as the right one but probably more like three times the size. From time to time I have a small pain in the left one (the large one) that feels kind of like its swelling too much. I know this hasn't been going on too long maybe a year or two and it is kind of embarrasing so I just wanted to get some opinions before going to the doctor; although, I am going to the doctor eventually. Thanks so much for your help
