Last week we went outside and it was very hot and I was wearing tight pants and tight panties and when I got home my are down there was itchy. The next day I think, it looked like a few little blisters. I have been shaving a lot lately too. But now they are painful pimples and some are drying up. But I do still shave and workout and get hot and sweaty and wear spandex. And they are not "clustered" or like really ugly. They kind of just look red and a little swollen and a little scab at the top. Help please I am worried.
