Help? Am i doing something wrong?

Hi! I am a teenage girl, and have been struggling with managing my hair down there. I am insecure to the point where i am avoiding going to the pool or lake with my friends because of it. I was self-conscious of the hair, so i tried sugar waxing and shaving, but both seem to leave ingrown hairs, shaving more (plus its SO ITCHY), and when i wax it leaves marks on my skin that dont go away and then i get ingrown hairs and it never goes away. I’m so tired. I just don’t want hair or red spots peaking out through my bikini/underwear PLEASE HELP ❤️🙏.
