Why does my vagina smell so bad? ⚠️TMI⚠️

I’m a virgin. I’ve never had sex so I know it’s not an STD. I know it’s not a UTI. I’ve struggled with this for a while like probably a year and a half. I’m really embarrassed by it. I would be so nervous to sit down places because when I would stand up I would sometimes leave like a sweat spot on the chair. I hope that makes sense. I know it’s really gross. But just sitting I could smell how bad my vagina smelled. It made me extremely anxious. I would constantly put on perfume to cover up the smell (I didn’t put perfume on my underwear or anything). I also don’t use scented soaps or bath bombs that I know can sometimes mess up your PH balance in your vagina. It was extremely bad when I would use restrooms like the smell would linger in the stall while I was in there & after I would walk out. It was so embarrassing. It makes me feel so insecure. I tried to tell my doctor and she just said it was discharge. And I hate talking about stuff like this so I didn’t want to tell her that I didn’t think it was that. Does anyone have this problem too? Do you know why my vagina smells so bad? Do you know how to fix it or stop it from smelling so bad? Please comment and let me know. Also I know this is really TMI and gross. Sorry.
