Girls I need some help 😩

So,

I shave my vagina... like most women do.

My vagina is fine for the first 2/3 days & then I get these red, itchy irritation bumps. (Pretty sure it’s called razor burn).

Im struggling. I need ways to get rid of it or at least calm it down.

It’s been a insecurity of mine for a while. Especially when having sex with my partner.

Any suggestions? Or things that have helped you?
