Waxing

Ok so I’ve never waxed anything besides my eyebrows. But I HATE shaving my lady parts. I have a hard time with the whole thing. I’m new to the shave club. I use a new razor, but still have cuts, and razor burn. I have tons of ingrown hairs, and red splotches from shaving. It sucks and I hate it. I moisturize and nothing helps, so I’m wondering about waxing. How long does that hair have to be? I’m thinking if I wax in the next couple weeks, I should let the hair grow so I don’t have any ingrown hairs. Any advice??
