First things first, try to shave a part of your body that is relatively harmless and out of sight such as your back or elbow to see if your experience any allergic reactions.
Some people are known to have breakouts as a result of hair removal in general, not just pubic hair cuts.
If you are a first timer or haven't done this much in the past or within recent weeks, your skin will take adjusting to the razor.
You will at first experience some mild irritation but that will go away as your skin adjusts.
Make the hair taut and begin trimming your hair to appropriate lengths prior to shaving with an electric shaver or wet razor.
Never share a razor with another person.
Especially not anyone named Bob.
In fact, don't even reuse an old one that you yourself have exclusively used.
Always use a fresh and clean razor as much as possible.
Apply plenty of shaving cream to the are you want to shave.
Allow the cream to settle into your hair and soften it.
Don't just get right to the shaving as soon as you apply the cream or gel.
Once it's shaved, make sure to clean the area thoroughly to prevent any stray bacteria, and other particles and hair from sticking around.
After you're done give yourself a pat on the back.
But the process repeats itself as your hair comes in full bloom every few weeks.
The hair may even grow back coarser than others and in greater quantities in some cases.
Also if you haven't shaved in recent weeks, the hair may cause itching as it grows back.
