Hi,
I actually have never had sex before, but I seem to have itchiness in my vagina quite often. Also there is a bump inside of my labia that gets worse around my period. I'm not sure where it comes from. My vagina also has a smell (embarrassing), but I don't know what is wrong. I am prone to yeast infections. I also have eczema, so I'm not sure if that is related. COuld it be diet related?

Please see a doctor about this condition. It could be related to eczema or not. Only your doctor can do tests on you to determine what this is. Any smell is not good either.
