If you've got sensitive skin like me, don't bother
Honestly don't be a baby and go for the wax, it'll be worth it
Whenever I shave down there initially it's awesome, perfectly smooth and pretty
Then next day it's a disaster, no matter when I do, I get red spots everywhere and they take about 2 weeks of lotion and sun exposure to go away, and they're extremely ugly
With the waxing you'll be a bit red for 24-48h max and then smooth as ice for 3+ weeks
If you must shave, make sure your skin is properly exfoliated (do it 24h before shaving though, otherwise you'll be too raw) and keep it hydrated too. Exfoliate 3x a week to prevent ingrown hairs, moisterise every day.
I still manage to cut myself from time to time if I give in and shave because it's just an awkward place to get to in some areas
Smooth out the outer lips if you do those too before sliding the razor on them, you'll have less chance of catching the skin (cuts down there not only hurt but can get nasty - humidity, urine... can lead to infection so watch out and if you do cut yourself use desinfecting skin healing cream)
