razor burn and ingrown hairs 😩😭

Shelby
Hey ladies! I need some advice. Every time I shave I get really bad razor burn and when it grows back the ingrown hairs are awful. No matter what razor I use or anything it's always the same and I can't use Nair products because it burns. And my boyfriend won't touch me if I'm not shaved so I'm not sure what to do. Any tips?
