Why aren't painless tattoos available?

Seems like it would be pretty easy to do. A few shots of Novocain, or some numbing cream applied to the area before hand would make the procedure fairly painless. Maybe the tattoo artists couldn’t administer the drugs themselves, but I’m sure they could partner with a doctor or nurse, even if just once a week or something. “Come in Thursday night for painless tattoos!”

On the other hand, is being willing to go through the pain an integral part of the act of getting a tattoo? Like a badge of honor? Would people who opted for the painless version be seen as ‘less than’ by others?

This all occurred to me while thinking about tattooed wedding rings. That particular spot seems like it would be very painful!
