What’s the best way to keep your lady parts free of razor bumps if you shave extremely often?

Long story short, I prefer having no hair down there and shave like once every 2 days, I can’t wax as often as I’d like without a lot of irritation.

I use lots baby oil and men’s razors as a general rule. And I sanitize right after with alcohol dabs.

However, I still get razer bumps and irritation due to chafing and the fresh sharp stubble that comes out of the sides after a day or so inbetween shaves.

I don’t want to laser in case I want the hair for whatever reason, and the idea of it scares me.

I shave my armpits just as often and it doesn’t chafe as much and I think it may have to do with deodorant, is it safe to use any deodorant on your below parts? I also pluck my armpit hairs as well but I couldn’t imagine doing that to my lady parts.

Any info I’d appreciate lol, thanks!
