Bumps on private part

I've had these issues for years now, and I never understood what was going on.

Every now and then, I have bumps show up on my private part some, times on the outside sometimes on the inside. I looked it up and saw that those were not ingrown hair. I have gotten tested every six months and have never been sexually active, and yet they keep showing up.

I really don't know why it keeps happening. Does anyone have an insight? If so, please help me 🥹
