Is this herpes or something else? Pic

I am 30 f and been with my 35 m partner for 5 years. We had sex last week and he came inside but I fell asleep before going to the toilet. A few hours later I peed but the next day I had a sore stingy vagina on the right side of the vagina opening. It was sore for about 5 days and then was feeling ok again.

I had sex again and this time the other side of the vagina opening was stingy and sore. I took a picture and this is what I saw…does this look like herpes or does it look like irritation or something else?

Hi Dara
it could be from friction, are you using a lube as well?
