Hey. I've had this for a couple of days but there is just one single small bump on the back part of my penis. It's kind of red. I just tried to ignore it. It didn't hurt or anything,not until you sweeze it. Well I was curious and I tried to pop it and it let out this clear liquid. There was still a hole. So I tried to let more liquid out.I noticed the more I squeezed it and let out more liquid, the bigger the bump got. I don't know what it is but can someone please help me beacuse I'm young and I don't know what it is or what to do.
