Because I don't like the stubble that results from shaving when the hairs start to grow back, I started using an epilator several years ago. The first few times where somewhat ouchy, but I wouldn't say that it HURT. The worst part is the 'seam' in the middle of the sack, the hairs that grow right there really don't like to be pulled, even after all this time. 15 minutes or so every 7-10 days keeps things nice and smooth.
I went to get waxed once after having used the epilator for several years. In terms of discomfort it wasn't any different, but it also wasn't any smoother or last any longer than what I do on my own, so I didn't go back.
If anyone is wondering, this is the one I use.

And no, it doesn't bother me that it says 'for women' in the description, I assumed that it couldn't really tell the difference. :)
Yeah used to have this done regularly along with my shaft and crack area. Its a great way to get smooth and after a few times really doesn't hurt. You have to help whoever is doing the waxing by pulling your sack tight but it's pretty quick. Would defo recommend!!
