Felt 2 bumps close to my vaginal hole but still on outside, looks like a boil/pimple not herpes. only had one partner, no pain/itch what can it be?

Pimple/boil/infex: This could be a few different things but most likely not an STD and most likely not something that will hurt you! It may be an actual pimple or boil though there are some glands in that area that do get infected not uncommonly. Try warm compresses to the area to try to get it to drain (do not pop). If still there in a week or too painful to wait, be seen for exam and possible incision/drainage.
