Shaving

I have been struggling so much with how my bikini line looks. I am severely insecure about it, I hate wearing bikinis in public. I just hate anything tht gives the opportunity for my bikini line to show. I watch tons of videos on how to properly shave and I thought I mastered it but I just keep getting bumps and ingrown hairs. I exfoliate everyday , i don’t shave everyday not even every week. Someone pleaseeeeee help me figure out what to do. It has affected my sex life because im so insecure of my body now. Any tips or tricks on how to remove them and how to properly shave ??
