My vagina smells like fart?!

Same here. Go to Walgreens or something an get a yeast infection kit and you can see if you have it or not then you can cure it. Or could be bacterial somehting i don't no how to spell the second one. Wait if you've had sex when you could have an STD.

Well it's physically and anatomically impossible for a vagina to fart. Whenever you hear noises like that escape from a vagina it's because air has been pushed into it, this usually only happens during sexual intercourse. So I'm guessing you must either be a guy with absolutely no idea how a woman's body works, or you have extremely bad hygiene to smell like that. You might want to see your doctor. lol :-)

Would see a doctor if it continues, but make sure your showering regulary and wearing clean underwear. You can get washes for those areas, with balance the ph and help with smell.

Just use some Febreeze it'll be fine. Just give it a couple of weeks.

Did you forget to take out your tampon?
And go see a doctor immediately!!!

Try using a douche.
