Based on the information provided this could be an ingrown hair, a simple cyst
or even folliculitis; but I can comment for sure only after physically examining the presentation, so please do not take my initial diagnosis for granted.
Advising a patient to pop any such presentation (which would take place under unsterile circumstances) would be unwise, as this could result in an infection or even a spread; I consider this to be unprofessional advise even more due to the location (region highly susceptible to infections).
As I have not visually examined you, the best advise I can give you right nownis to keep the area clean and dry, wear clean and comfortable undergarments, place a sterile pad in place (in case the boil ruptures on its own), take warm sitz baths with epsom salt several times a day and apply warm compresses through the day. These measures will promote quick healing and avoid infections. Please also wash the region with a mild soap when/if it does rupture/pop.
Hope this helps.
