Help

around 3 months ago i had a cluster of spots on my upper thigh and since then nothing all, doctors said it looked like a fungal infection. (see picture) recently I have had a lot of tingling feelings around the vulva and some almost stinging pain its much more sensitive and raw I havent had anything else show up other than straight after i had sex once with a red irritated bit inside my vagina. I am so confused what this is and im so concerned. Does anyone else have really irritated vaginas, is this normal? i dont know if its just hair growing back thats making it feel like that but i never had this problem before. Thank you
