Suggest Remedy For Soreness And Cut On My Vagina

I had sex with a friend 2 days ago......the right side f my vagina was swollen and sore after. he sucked very hard on my vagina for a long time to the point it hurt, everything else was very pleasurable. now it is not itchy, but it looks like I have a cut on the top part of my vagina and the lip on the right side is black it feels lie a scab from a cut and the skin is peeling, I am still a bit sore there is no discharge or burning when peeing or itchiness.
