Brazilian Wax

I have my first ever Brazilian wax (also first ever wax anywhere but my eyebrows) in exactly two weeks. I shaved down there this morning because I’ve read two weeks worth of growth should make it long enough for the wax to grab hold of the hairs. I’m pretty concerned about the pain, because I don’t have the highest pain tolerance; I just can’t stand shaving and the ingrown hairs I get from it so I’m thinking I’ll try anything once. I’m hoping I like the results🤞🏼, any advice?
