I have sex with a boy I did not know very well about six months ago and have not had it since. about two weeks after I slept with him, I found a pimple on my pubic area, I shaved it to look at it better and more appeared but they seemed like ingrown hairs, then about two days ago, there was what looked like blackheads on my inner thigh so I squeezed them, and then overnight I got open red puss sores. they healed and then they appeared again a few days later. also preceding this I had slept in a wet bathing suit for a couple of days because I forgot underwear on a camping trip.
