A couple weeks ago I shaved my entire public region for the first time. I also had sex that night (which resulted in a bladder infection). After a few days I started having a very itchy pubic region and would scratch it a lot. This went on for several days until I inspected the Region. There are terrible red spots (flat spots) and a lot of them have white dry skin that flakes away very easily. I also found a bump filled with pus today that popped with the slightest touch. What could this be, skin irritation? Rash, eczema? I really hope it's not an std, but it isn't on the actual vagina, just above where the majority of the pubic hair grows.
