What’s going on down there?

I know this is gross but is this normal? My panties are always wet and sometimes I know for sure it’s because I’m sweating down there but a lot of times it’s like my bladder released a bit and then sometimes it’s white discharge but it’s a rare occasion when I find my underwear dry. It feels like I have no control or understanding of my own vagina.

I’m 21 by the way and I’ve never had bladder problems. This has been this way for years, I can’t remember when it started happening or if it was always a thing. I’m just hyper aware of it now and I’m wondering if I should ask my doctor about it or something?
