In my opinion if you use a properly hydrated lather, it shouldn’t prevent you from seeing what’s going on.
I’d focus on getting as much water as possible into your lather. Then use as mild of a DE razor as you own.
I’ve personally never had trouble using a DE “down there.” I typically use a Merkur 34C for this and have had great results.
Granted, I don’t have lady bits down there so I can’t speak to those specific difficulties. I have to assume though that you’d get good results with a properly hydrated lather, a mild razor, and a good deal of care.
It could be worth trying milder blades. Feathers are definitely on the aggressive side.
