I use a manual shave most of the time, sometimes with an electric trimmer for "down there". However, if I'm stressed, I'm likely to start plucking "down there" to relieve stress (if my eyebrows are done already) - it takes forever, but is therapeutic and the hair stays gone for a long time.
I use a manual razor, though I would like to have one specifically for "down there". I put shaving cream on simply because it doesn't have the potential to cut or nick me. I always make sure I rinse thoroughly afterwards.
