Hello, I Am 18 Years Old And I Recently Started

Hello, I am 18 years old and I recently started taking notice to some lymph like bumps on my penis. They do not hurt really unless something presses fairly hard onto them. They get harder with erection. What is worrying me is that I think I may have had these for a while and I still continued to masturbate somewhat frequently. My questions are, and forgive me if these have been asked too many times before: 1) Assuming I have had these lymphoceles for a while, would they have already caused permanent damage?
2) What are some suggested methods to helping these bumps go away?
NB: Ive already stopped masturbating and waiting for results, hopefully. I just want some peace of mind.
