Ive been having sex with the same person for about a month now. Never had this happen to me before. I did shave my anus area for the first time before the last time we had sex which was about 5-6 days before this showed up. After the last time we had sex which was the 18th and today is the 25th, i did have a yeast infection but ive noticed i get those often. This hurts and just want to know what it is.
You should see a doctor and get checked to see if you have a condition known as lichen sclerosus
