Placement wise the most common placement for a tattoo like that seems, to me at least, to be the outside of your first finger, so you can hold it up to look like a 'tache / whiskers, whatever (I don't get it, but hey ho.)
Being tattooed depends heavily on who is tattooing you bit generally feels like you are being scratched with a warm pin, it's odd, more than painful.
Anyway, if you go with placement in the pic it shouldn't be too bad. People like to make out that getting a tattoo really hurts, most of the time it really doesn't.
