HELP!!! Down There Hair

Bl

So I like to have it all off but whenever I use nair it doesn't take off all the hairs , when I wax it's painful , when I shave I get major burns and bumps .

Last night , my boyfriend texted me asking if I wanted to meet up with him today. So I know exactly what he had in mind and I wanted to be extra clear. I had a bit of hair down there and didn't have time to use nair , I shaved and now I have TOO MANY bumps and ingrown hairs . it is painful and makes my vagina look unflattering.

How can I clear this quickly ? Also comment below how you usually get rid of hair down there without problems.
