Hello everyone, I'm 21 and have been engaged for a year. I've only had sex with my fiance since we got together 2 years ago. Recently I've had intense itching right at the opening of my vagina and slightly inside of it. It itches so bad that I dread going to work. It itched for about 4 days and then stopped. It was gone for 2 days, then I had sex and put a thong on afterwards. After wearing the thong all day the itch came back. I took it off and slept without underwear. When I woke up the itch was still there. I've been putting vagasil on it but it's not helping. It's an intense itch that won't go away. I've been drinking lots of water and showing daily. I was tested for std's and I don't have anything. Also, there is no discharge from my vagina. please help!
