Talk to Gynecologist on Vaginal Pimples

I have been developing small pimples on my vaginal different areas from past 2months One at a time.... And resolves on its own in 1 week.. Not painful...... Sometimes pus filled sometimes not... Developed once in clitoris resolves on its own and after sometime 2 times at inner side of left labia minora then gone then again at inner side of right labia minora one...

Sometimes cause a bit discomfort while washing with shower. why is this due to? may be moisture? after washing dont dry....or vaginal imbalance? what to do..

ps. i dont wear underwears. married but no sexual activity from past 2months (just one time in between).
