It's itchy too and I'm not sure whether it smells like rotten egg or fish but it is unpleasant. I had it last month but it stopped until a few days ago when I fooled around with my boyfriend. I don't know if it's coincidence and I'm still a virgin.
Could be bacterial vaginosis.....if you're a virgin..however and your boyfriend performed oral sex then his saliva may have triggered something with your ph level..........a woman's body is very unique and different in its own way........just be careful.....there's over-the-counter treatment for b.v. or you can go to the doctor and get prescribed antibiotics.............I have been suffering from back to back b.v. occurences for the past 6 months ....smh.......but consult a doctor so you'll know for sure what it is
