Shaving question

🐝

For about 6 months now I've been extra sensitive to doing any maintenance down there. I used to shave but I get very bad razor burn and ingrown hairs. I changed to a Nair-like product thats specifically for the genitals but it also results in huge, painful, super swollen ingrown hairs. I now haven't done anything to my public hair in like a month and all has healed but now it's getting longer and I have the itch to do something. Anyone have any tips? I don't mind hair down there but to an extent. Anyone use any products to simply trim up? Thanks in advance!
