Ok so I’ve had these bumps on my penis for 5 years, and don’t know how

So when i was 14(virgin) , i was messing around with this girl 14 (virgin)that use to rub my penis with her feet, it started out ok but i noticed that afterwards a little white bump would pop up the next day or 2 on my frenulum , anyway me being a dumb kid i let it go on for 2 weeks and then i had enough, told her that its not satisfying for me but i never told anyone ab the bumps because i was scared and they would think i was having sex, now that im 19 i dont care, i need to get rid of these bumps and enjoy my life stress free. They do not hurt but i tried to pluck at one and i think it got bigger, does anyone have these bumps? what are they? and how do i get rid of them?
