Hi i have a problem i noticed tonight when i masterbated Below the head of my penis was a lump upon inspection it felt like a cluster of vines. I didnt take it as anything bad so while masterbating i noticed around the lump fluid began to build up, right upon the point of ejaculation the fluid increased leaving my penis looking like someone stuffed half a golf ball under my skin. Could it be that i ruptured a vein and its just blood buildup, if so how can i fix that. Or is it something that will go away tomorrow. PS. I feel no pain when i squeeze the lump
