Try waxing instead of shaving, and make sure to select the proper wax for your skin because even wax can give you bumps and maybe try using an oil after shaving such as coconut oil, vitamin E oil or tea tree if your skin likes it.
You should try using bikini zone medicated after shave creme/gel. It soothes and prevents the redness. U also may be dry and need to use some sensitive skin and unscented lotion (but not in vulva, just outer area). I use a men's Mach 3 razor and it works better than any female razor I've ever used.
I know it sounds embarrassing but you should see a doctor
Idk but can u please tell me how to ask a quistion its urgent and im fr about to cry
