I've noticed sore on my labia

So about a week ago I noticed a sore on my labia. It's just one. It feels like an open sore. It doesn't hurt unless I touch it, it's like a discomfort. Not really hurt. Just uncomfortable. I noticed it like a couple days after I had sex with my bf. idk if it was always there and just now getting bigger, but i need HELP!

Sounds like it may b a risen or herpes. I have genital herpes & I only get one sore during an outbreak. You should go get it swabbed for testing ASAP

I am pretty sure that is not BV, see a physician

Looks like herpes, dont have sex or you will transmite
