I noticed about a month ago these weird bumps on my testicles and the base of my scrodom. I have sexually active (I haven't been for a year tho). I only see them when I stretch my sack. There the same size I can't seem to find anything about them I have seen some people but they seem to have other problems. Me and my gf are going to have sex soon (It will be her first time) I want to know if its harmless or not. I read somewhere to use warm salt water so I will try that. But I wanna make sure its nothing major I know its not an STD. I always get checked a week after having sex. Some times I wait (Due to some STD's taking longer) Please someone help me so I know if its nothing or something I should probably go to the doc about. (I'm 16.)
