You probably have ingrown hair, or razor burn. Try using a moisturizer.

It's really sensitive down there, so you have to be really really careful when using a razor. Not just because you might cut yourself severely, but because the skin isn't used to being shaved. If you're going to do it again, do it while in a hot shower so the skin is moist and the hair is easier to remove.

Use a moisturizer on the skin until the hair has a chance to grow back. You may be experiencing discomfort due to razor stubble.

thanks guys...i bought some lotion and a 6 pack of beer....1 of these better help or im saying goodbye to this cruel world....

Very funny! You could just try shaving again! That will get rid of the stubble. My husband shaved for me and complained of the itchy rash. Lotion did the trick. I hope it helps and the beer may help you forget about it for awhile. Time will take care of the problem as well. All the best.
