I am 17 years old, and I've never had sex. Around a year ago, I noticed a lump inside my urethra that would cause slight discomfort every now and then, and pressure caused pain. It is still here a year later, and it's still the same size, and hasn't caused any other symptoms. I've done quite a bit of research, and I believe I may have a cyst in my urethra. What do you think?
