Skip the shaving cream and sharp razors and get a hygienic blade electric razor! No cuts and it makes you baby smooth. No need for shaving cream, water soaks, deodorant, anything! It works wonders

Simple solution, don't wear any pants.

Wax

Good razor and I use hair conditioner. Eventually you will be great well most can get used to it also deodorant helps razor burn the white kind not gel

First time is always the worst OP, eventually you will get the hang of it and lots of good suggestions here. One thing I find helps more than anything, get a non electric razor and shave in a HOT shower then a really good quality aftershave balm, not liquid get a balm it's like a runny lotion and makes worlds of difference.

Practice makes perfect

Baby powder should help, or Butt Cream. Not even joking here, diaper rash ointment does wonders for razor burn. And as others have said, shaving cream and a fresh razor should help next time!

I'd recommend using a creamy body wash and then a bikini area ointment afterward. You can also use a solid deodorant in a pinch to prevent ingrowns. Practice makes perfect!

Use conditioner to shave with and a sharp razor. Get baby oil and use it on the area for two days after shaving. Make sure you have alcohol or neosporin for any nicks or cuts from shaving unfamiliar curvy areas. Good luck, OP!

Well, time to put on Amanda Palmer's "Map of Tasmania" for a few days. On a more serious note, trim, trim, trim, as much as you can before you ever take razor to that area.
