it's simple really, and depends on your self control a bit, the shaver you use, how often you do it and how much time you have.
My best advice:
- Do it in the shower, and make sure you use some kind of soap
- use the Gillette Venus lady shaver, the one with the gel lips, or a similar one
- Only use a new blade in the beginning.
- Only shave your balls, not the wishbone above you penis. Unless you are experienced.
- Instead of single strokes like when you shave your beard, try smaller strokes, cleaning the hair off the blade often.
- Shave often, as the first couple of times it will be itchy, and you might cut yourself. But it goes away after a while
- Stretch the skin in the beginning, to learn how it works. Once you know how it is done, you can do it without stretching too much
- If you are very hairy, try and use a Trimmer to reduce the hair a bit, but be carefull, normal trimmer will cut you
After a couple of times it will become rather easy, but if you are to scared, then try shaving your armpits first, much of the lessons you learn will be useful for shaving your nuts.
And the most important advice I can give you is, take your time. A fast shave is only for the well experienced shavers, and even then, you end up hurting yourself every now and then.
If you shave once a week, it will soon become second nature, as the hair stay short, your skin get's use to it, and you get use to the feeling. Try wearing boxers in the beginning, so it does not itch so much.
I can shave the nuts in less than a minute, and it doesn't itch at all, neither does it grow in nor do I cut myself. I do however have many years of experience. And my armpits are also shaved, always.
