im 18 years old and recently discovered i have a cysts on my testy. i do have sex alot n wondering could that be the cause of the cysts? do all cysts have to be removed? mine seems as if it has already gotten smaller from when i discovered it, around a month or so ago. is this a good sign? it doesnt cause any pain or discomfort ever. is there any way to prevent this cyst from getting larger? does sex have anything to do with it? i dont know what kind of cysts it is im not sure if its attached to the testy or not, it floats around. any information greatly appreciated thanks
