Struggling with Hygiene!

I’ve been struggling a lot with my hygiene lately. I have noticed that it’s very difficult for my deodorant to combat smells of sweat and must and the interaction between the two is often an unpleasant smell. It was suggested that I try an antibacterial soap for my armpits and it worked for a while but recently, it has become a problem again. I’m also starting to experience issues with smelly sweat on my labia. I shower once a day, I clean myself thoroughly, and I never use the same rag or dry-off towel for too long. However, no matter what I do, I get a sweaty, oniony smell on my labia. Even if I’m not active during the day! And it’s currently cold where I live so climate isn’t a likely factor. I’ve tried to go without underwear and with loose, cotton underwear but it makes no difference. I know I don’t have any internal vaginal infections or anything like that. Does anyone have any idea what’s going on? How I could fix it? I have used Dove’s pink/rose unsecured soap all of my life.
