I'm a 19 year old female who has been having problems down there since I lost my virginity 4 months ago. First it was a urinary tract infection (diagnosed) in November. It was treated and there were no more problems. I got a pap test around the same time and it came back saying I had a yeast infection, which made sense because I had been experiencing slight itching and redness (which I thought was normal because it was mostly right after sex) for some time. I went and got the Canesten 7 day treatment and everything was fine again, but at the same time that I was treating the yeast infection I felt like what was another UTI so I went and took a urine test which confirmed that I did have a UTI (so if you're keeping up with me, I had 2 UTIs, one of which I had a yeast infection at the same time). I have only had one sexual partner and we have always used condoms, but recently I found out that he's been with a lot of other girls which has worried me. I went and got tested for every single STD possible and it all came up negative (Trichomonais, chlamidia, gonnorhea, HPV, Syphillis, HIV, Hep B & C). I also had a swab done revealing that I had no irregular cultures or yeast, etc. Ever since I had my last UTI (at the end of january 2010) I just have not felt the same. I have slight burning in my urethra, and I feel it before urinating but not during, and sometimes after urinating. It's not so much painful as it is uncomfortable and worrisome. I also notice this mild burning at the bottom of my vaginal opening, but this is a different feeling, almost as if I have some tearing. I have had sex two times since being tested for STDs but have not noticed any other symptoms, and there is little discomfort during sex. I sometimes have mild bloating and abdominal discomfort even after urinating and emptying my bladder, so I'm wondering if this could be a sort of bladder or urinary problem; I'm almost convinced it isn't an STD after testing negative but I'm still worried. The only times I don't feel any burning is when I have drank alot of water and relieved myself. I have done other searches on google and other women have been complaining about the same thing, so at least I don't feel alone. I am going to the doctor's next week but I just want everyone's input. I am probably worried more or less because I have NEVER had any kind of problems down there when I was a virgin.
