Shaving down there?

Grow out your pubic hair and don't shave for three months. The bumps should fade. I would say let go of the men's razor. Too harsh on women's skin. Try the one bladed bic's razor (sensitive). They should fade.

The correct answer is to get it waxed. It will not grow back as fast ( although it might hurt if your hair is thick) If you want to continue shaving... then use lots of shaving cream, clean area well and always exfoliate and tweeze out any hairs that start to form into ingrown hairs. 

This isn't medical advice at all but you might be prone to ingrown hairs. Both my sister and I have it and hers can get infected to the point where she needs to have incision and drainage done. I would try tend skin as that's supposed to help with bumps. There's also a brand called Happy Girl (let's face it, it's gender neutral products they're just marketing towards women) that sell serums and masks to help with bumps and in grown hairs. 

Have you tried applying coconut oil first? Ever since I started using it for shaving I've never had any skin irritation. I apply it to the area to be shaved several minutes before showering/shaving. Then I apply a little shaving cream so I can see where I've shaved. Please try coconut oil, it is excellent for protecting the skin and you'll feel really smooth afterwards as it is not washed off with just plain water. 

I'm a guy, but I'll keep it polite.  I've been shaving three times longer than you've been breathing, and I know those red bumps very well.  My beard is like barbed wire, but my skin is like a baby's bottom, so our situations are similar when it comes to shaving.

The best thing I ever did to eliminate razor bumps was to buy a Philips One Blade.  The next best thing was to use Gilette Sensitive Skin with Aloe and keep my blades new and sharp.

The One Blade doesn't cost much, and it gets 99.9% as close as a blade.  It takes longer (you have to move slowly) and you can still feel micro-stubble (we call it 5 o'clock shadow), but it looks like you shaved with a blade.  And the best part is no or very little mild skin irritation.  The bumps come from the blade removing a layer or two of skin, and the skin grows back over the hair.  The One Blade doesn't remove any skin at all, so you won't get the red bumps.

why are you shaving in the first place?

Maybe it’s the razor

Shaving is what you are doing wrong.  Leave it all alone.

Use shaving cream. 

Why don’t you ask your friends or your mom how they shave. 

Are you using the pro glide. 

Have you tried asking a barber to do it for you. They’re really good with a straight razor so you should get a smooth shave. 

You should ask your mom about this kind of stuff
