I wax just the base and trim the rest (I don’t want anybody looking down there and making comments about “split ends”). The waxing hurt like hell the first time, but you get used to it after a while, or develop better technique. After a long while, the follicles get the idea that they’re not wanted and start to shrivel; the hair grows in finer and finer and (supposedly) stop growing in. The waxing does not have to be done that often, maybe ever week or two when I first started, every three or four weeks now (depending on the time of year).
I once asked some kind lesbians who run a laser hair-zapper shop in the neighborhood about zapping the hair. They said that they’ve done that for some customers, but the process is very slow and expensive, and has to be redone from time to time; it’s not as permanent or sure as sticking a fine wire into each follicle and electrocuting it.
As for the combo of laser + penis, well, the laser beam is no bigger than a thin wire. We’re not talking about a death ray. It wouldn’t be much worse than sticking pins into the thing.
Needless to say, I didn’t go for the laser.
