Back story: For my entire adult life, I'd only been with women (and not very many) until this year, when I decided to try having sex with men. Which means this is my first time ever worrying about stuff like this. I may be overreacting but I'm terrified because this is all so new to me.
I had unprotected sex two weeks ago with someone I hook up with on occasion. He has informed me that he is STD/STI-free, however, I have no proof of that. I also, stupidly, allowed him to go from anal to vaginal without a condom or cleaning himself off, which I know was a very poor decision. Exactly one week after the sex, my vagina began to itch. I noticed it immediately after I got out of the shower and finished shaving, so at first, I chalked it up to that. I assumed maybe I got some shave gel in there or something. I got my period the next day and the itching continued on and off for days. I have also noticed an unpleasant odor that I'm not used to. It's been about a week now and the odor is still here. I do not seem to have any discharge, though. I thought it was possibly a yeast infection, but the smell isn't very "yeasty." I took an at-home vaginal infection test and it came back negative, but I don't know how reliable those things are. I also got tested for a UTI today, but I'm not sure if a UTI can cause an odor?
Basically, I do not know if I'm freaking out for no reason or if I should go to my gynecologist. I was just tested for all STDs about three months ago and I feel silly for asking her to test me again, but like I said, this is the first time I've ever been concerned about STDs. Anyone have any advice?
