What kind of soap do you use down there?

I’m looking for something gentle and unscented. I looked at all of the soaps that are marketed for vaginas, like summers eve, and they all have scents and my skin is very sensitive so that’s a no go for me. I’ve been thinking about Castile soap because that’s what I use for my hair and body, but all of the ones I can find are scented as well. And yes, I know some doctors recommend only using water down there but if I do that then I feel dirty. And I only use the soap on the outside so it’s al good. Please throw some soap suggestions at me if you have them. :)
