How on earth do you shave your bits and it not be a nightmare?

I’ve used nair, men’s razors, women’s razors, shaving gel, cream, oil, exfoliation, and nope! Covered in bumps and acne with 2-4 hairs now coming out of every pore
It’s so frustrating (and itchy) I just wanna be smoooth and clean

I’m too much of a baby to wax myself and too young (and scared) to let anyone poke around there but I’d like some help!

Should I just leave it alone for a little? The last time i shaved was a week ago and it’s kinda grown back but some spots are still irritated
