Hi, i had sex about five days ago and since then my perineum is very swollen and it only stings when i touch it but doesnt hurt, it looks very red and sore, i went to doctor however she said she doesnt know what that could be and took some swabs to do test for std however i know for sure i dont have this as i had it done 2 weeks before all this happened, is there anything i can do without me having to go back to this doctor( who seems not be able to help me anyway) many thanks
