You and your hoo-ha should be pretty well acquainted by now... you know her smell, and when it's off it can be a little bit mind-boggling.
Your natural aroma is just that, natural. But if you're noticing a big difference then it's probably depending on a wiiiiide range of different factors...
Basically, you are what you eat. The foods you eat can definitely change the way your vagina smells. Remember when you ate asparagus for dinner that night? Thanks Mum.
All you have to do to avoid foods changing your odour is to wash it all down with plenty of fluids. Water fixes everything really.
Depending on the type of underwear you wear, the smell of your gurlll can change. Some materials can trap moisture which can make a smell more prominent. Go for lighter fabrics that breathe, like cotton. It's all about dat air flow! Don't trap your honey she needs some air.
Just like all the other nooks and crannies in your bod, they get stanky when you work up a sweat. Same goes for good old vajay down there.
All you need is a good shower.
Chances are the smell you can smell is non-existent to other people, so if you're trying to cover up a natural odour with a strong smell like deodorant or perfume, you're wasting your time and could also be making it WAYYY worse. The skin on your underarm is pretty resilient to deodorants, but your vagina is so incredibly sensitive.
Sprays and cover-ups can actually cause irritation and that's just nahhht what you need RN.
Obviously there's a whole lot going on down there when you're on your period. Naturally the smell can get a little more intense, but that's nothing to worry about. What is a problem is if you forget about your tampon, or aren't changing your pad enough - then it can really cause a smelly odor. Ick.
Worst case scenario, a bad smell can be caused from a vaginal infection. You'll know if it's an infection because the smell isn't the only symptom. Look out for abnormal discharge, itching and irritation. If this is the case, see a doctor and they'll prescribe you will the right medication or creams that will usually rid you of your problem very quickly!
At the end of the day, all us gals have our own gal down in our panties that has her very own smell. Nobody smells the same, and unless you are noticing a major difference in what's normal for you, then you should embrace your vag the way it is.
