I spent the weekend with a guy and we had a LOT of sex. I noticed on the second day that it was a little painful and burned when I peed. Today I looked and it seems like I have chafing or a rub burn on my labia and near the vaginal opening. I guess we were a little too rough. I’m pretty sure it’s not an infection or std and we used condoms. Is there anything I can do at home to help this go away or do I have to make a Gyn appointment for it?
