It can be difficult, but I still think a wet shave is best. Keep 'em taught, be careful, moisturise. And to stop the itching after a couple of days of growth, talc your balls after!
I get waxed bare at a salon and its not as bad an experience as some would think and the end results are worth it. Feels cleaner and fresh and sex and oral feel great too. I prefer it and my other half does too
