Really embarrassing to ask…

Lately I have noticed vagina stinks really bad. It’s not my discharge or actual vagina. It’s like the side between my vagina and upper thigh. It stinks bad almost like really really bad body odor. I can be fresh out of the shower and 10 mins later it stinks again. I can even smell it through my jeans sometimes. I don’t have to sweat for it to stink. What could this be and how can I fix it 😭 the red circles is where it stinks
