In my experience, I have found that this works rather well.
If you have long pubic hair, use a small pair of scissors to trim the hair down first.
Both men and women should choose a female razor, rather than an ordinary safety razor.
I have found this to be true. I was told by my doctor once, that if I were going to shave, to use an upscale brand type razor because before hand, when I shaved, I would buy the cheap razors and end up with nicks, cuts, you name it! lol But this is just what our doc told us to use. We actually use a Mach 3 as well. (LOVE Mach3's)
Wet a washcloth and lay it over the entire pubic area for two or three minutes. Alternatively, take a long hot bath or stay in the shower for a while making sure the pubic area receives a lot of water. Pubic hair needs more time to soften for the shave.
Apply plenty of shaving foam or gel over the area and leave for a few minutes to soften further. Ordinary soap is not suitable as it does not lock in the moisture to the hair the way a shaving preparation cream or gel does.
I used soap a lot too, and it did irritate my skin. As we know, women are sensitive down there and need something that isn't going to cause more harm than good.
Shave upwards against the grain. I usually shave with the grain once and then again, against the grain. It works well for me, but you might want to try it and see how it works for you.
If you shave bare, it can cause razor burn.
Massage unscented Vitamin E oil into the pubic area after shaving.
To keep my pubic area moisurized and keep it from getting irritating, I rub vitamin E on me and it does work wonders. I have tried lotions, creams, and all sorts of things. I also use Nivea cream, in the glass jar and it works GREAT!!!
Everyone has great suggestions. What I suggest, is that you find whats right for you and follow it.
Best of luck!
