So the comfy moment when you get tattoed is basically when tattoing stops. Indeed tattoos not certified comfy. I know some fellas that find fulfillment through the pain received during tattoo tho but as they are into BDSM cacas it not a valid argument.
I personally have some little ones on my hand I made myself long tmes ago with india ink and a sewing needle. It was not painful but not really comfy, although I enjoyed the moment in a certain way.
