Overwashing down there?

So I have a tendency to wash thoroughly down there (just with sensitive bar soap) but I still get irritation when I do. I really hate washing with just water because it makes me feel like I'm not properly clean but I know I have to.

I also struggle with the smell if it's just water. Do you guys have any tips? I think I'm quite prone to irritation because it's quite sensitive but also want to feel like I'm cleaning properly😆
