Here's a little advice from a hair removal pro:
If you have thick hair to start with, then use a trimmer to trim it down. Then get a can of Skintimate Bikini and Underarm shaving cream (I know it's supposed to be for girls, but it really is a lot better than men's shaving cream. Just tell the little guy at the checkout counter that you're going to kick his ass if he starts to laugh at you!). A Mach 3 razor is what I'd recommend. Then get a tub full of hot water and go to work. I'm a big guy, so I find that arms, shoulders, chest, and lowerlegs are best done while sitting in the water, and then I stand up for everything else (and yes, I do mean everything else). Whenever you start to feel even slightly prickly, do it again. It's 5 times faster if you catch it before it gets where you're able to tell that it's growing back. I recommend Jergens Shave Minimizer lotion, it helps the hair grow back softer and with daily use (after a couple months) it can put off your shave for another day or two. The lotion also helps your tan have a little extra glow to it. I find that hair removal creams and sprays are harsh on my skin, and usually take longer than shaving once you figure in the time that you have to wait before you remove the stuff. After the first few times, you won't cut yourself at all, and you'll be able to do it rather quickly. On a side note, don't get trimmers anywhere near your nutsack, especially if it is a little saggy. The nutsack skin can get caught in between the clipping blades and it will bleed for days on end. A regular razor with shaving cream are the only thing I would touch my boys with. If you can get them nice and cool (aka, standing up out of the hot water in a cool room), that'll shrink em up so that they're easy to handle.
