I'm 16 too and I get this sometimes, I also am not sexually active either, I'm pretty sure it's common and just hormons. So I have heard.
Could also be something ur eating
It doesn't burn, itch nor sting. It's just smelly.
You need to be seen by a doctor it could be from a number of things.
Sounds like maybe a yeast infection or bacterica vaginosis or uti can be pretty smelly as well.
It sounds like a yeast infection.. Does it itch or hurt to urinate?? I myself am also i very clean person and OCD about that area.. I was told if you clean to much especially if you use body wash near it alot or bubble soap in bath water that it can also cause a UTI
