TMI:I can’t shave my vagina without cutting it a ton

So I need major help EVERYTIME I shave I cut my vagina. Like a lot not a little bit like 10 little cuts all over and then I also get ingrown hair and razor burn. I’m trying to figure out how to stop this before summer because it looks terrible. I wait like 4 days for the hair to grow so it’s long enough I did stop shaving for about a year is that maybe why it get cut and irritated so easily I just need a way to make the bumps go away tbh can you help!
