Well I think you just have a smell that is a little stronger than most people. One thing you could do is using a spray down there. FDS or Sure deodorant spray. That gets rid of the musty smell. Make sure it does not have talc in it. That is why I use Sure it has no talc. Guys could use it too. I always get the unscented one. Safer. I know when you urinate that makes it smell stronger so when you do that, wipe off with baby wipes. You should be good from that. Also drink more water, it dilutes the strong smell of the sweat.
