I don't want to be told how shitty this situation is....just please tell me what you think about the symptoms.

Especially if you've had an STD before

I've never had one. I always use protection.

About 3 days ago me and a tinder date got very drunk. Went back to his house, and I was very out of it. He knew I wanted to use a condom. I ended up passing out, and he started having sex with me while I was out. I came to during it happening. I know he didn't use a condom. (Please, again, don't comment on the situation. I know)

Yesterday I started itching around the labia and kind of on the inside. Kind of like a yeast infection. I'm going to get tested tomorrow.....but how likely is this to be an STD?? Like.....can I have symptoms THIS quickly?? Should I be really worried about this?
