Hello I recently had a pelvic exam done and got tested and everything came back negative. About a week later, me and my fiance had sex and that night i used the bathroombright after sex and i was fine. But right the next day in the morning I woke up and I went to the bathroom and noticed a stinging sensation when pee got on a certain part of the inside of my vaulva so I grabbed my cell phone and took a picture of it. When I took the picture I see like a red round looking scratch. I jumped in the shower then washed up then got out and took another picture like 1 hr after and it appeared to turn white like it was healing or something. Now it's all of a sudden red agin I figured I might just be irritated from my vaulva rubbing together and from me Waring underware all day. Me and my fiance has been clean without any stds and or stis so I'm wondering how I all of a sudden got this the next morning after a sex night. Could it be a scratch form dry sex or ruff sex? Could it be psoriasis? how a irritation rash from using different soaps or using the same rag that I wash my underarms with on my Virginia? I put some patrolum jelly on it to stop the pain when i close my legs and my vaulva lips touch each other and that seems to sooth the irritation but I need to know what it is or what to do. Its only one sore and it's only one one side. It hasn't spread either but it tends to feel ichy when my Virginia becomes wet.
