Performing BBBJ on unshaved guy's is also pretty risky and not attractive !!!
Perhaps you can open a barber shop specializing in pubic shaves, with this statement as your marketing mantra. I do think there is a need for such a service. It is very hard to shave the underside of the scrotum and probably much safer if you have someone else doing it.
Perhaps you can call the business "Booker's Pube Busters"?
By the ways this business advice is free to you.
