Cremo shave cream(its the best at walmart)..do it in the shower...first few times was scared...now not much of a problem or time consuming at all. The Cremo does make a difference and is cheap...use it on my face to.
Used Nair once and it burnt me junk something awful - I even used the one for sensitive skin. I looked like a mangy possum and put me out of commission for a couple of weeks.
For me, dry shaving works great if I let it grow out for at least a week first. Smooth as a baby's ass for a day or so.
There's also Nads which is a close cousin of Nair, supposedly made for the male genital area. Smells super horrible! And seems kind of corrosive if you leave it on too long, but I suppose it works if you want to air out the house afterwards!
