Boil-like bump around genital crease.

I get recurring bumps in my genital area that follow the same pattern every time. They start small, like a hard mosquito bite. Over 2-3 days they get more raised/bumpy. In the next 1-2 days a whitehead forms and it pops on its own. Within 1-2 days after that, it fully heals. After healing, it leaves a small hole that doesn't hurt, which turns into a blackhead that I usually clean out. These bumps usually appear along the same crease/fold in my groin area, but this time time appeared in a slightly different spot for the first time which is Labia majora near vaginal opening. This cycle repeats every 2-3 weeks.The bump is roughly 1-2 cm in size. I don't have fever, significant pain, or foul odor with these. I'm 29 years old. What could be causing this recurring pattern, and how can I prevent or treat it properly? Is this likely to be folliculitis, ingrown hairs, or blocked glands? What's safe to use on it right now, especially once it's already popped?
