Razor scars on vagina/bikini line? How to avoid/cure?

I have a bunch of razor scars which make me very self conscious about “down there”. It’s not A LOT a lot, but enough to get on my nerves lol. I’m still a virgin, and if the time came to lose it, I’d hate for him to see me like that. How do I properly shave down there and what’s the best product to use in order to avoid these bumps and scars? I’m not sure if this is a thing but how do you properly get into “the cracks and crevices” without cutting anything? Waxing isn’t an option, lol. Thanks in advance.
