Yes, it is true
I guess if you believed that if would work it could have some placebo effect.
To be honest…I would not chance it. I would rather have a headache rather than both a headache and terrible vaginal burning…WOW!! Actually…that kinda burns me even just thinking about it….
no! it will not work!!!
There is anecdotal evidence that this works, however there is real evidence that exposing your genital areas to foreign substances, particularly acidic things, can throw off the pH balance in your vagina leading to yeast and bacterial infections, and worse. Additionally, I would imagine that doing this would be painful. Perhaps, the success people have had with this simply stems from the mental distraction resulting from the new discomfort.
