Ok, so I used a pump last week. First time user of the pump and the cockring was too small, it hurt! I quickly took it off but the area that was hurting has one irritating bump that has arisen as a result. There are actually two bumps but only one stings.....what is this? And have I seriously injured my penis? I didn't even pump that much and the cockring was on for less than 30 seconds. Thanks for your help.
