I have about 30 hours of tattooing done so far, including my face and knuckles and one of my lower legs is solid black. I dont have any gential tattoos as of yet, but i have them planned anyway. I however am an accompished piercer and scarification artist so i have been around lots and lots of tattoo artist. So i can tell you from what i have picked up. That the penis is a very quick healer do to the vast amount of blood it recieves, tattoos on the whole will take about a week to 2 weeks to finish inital healing to were its not inflamed and such, just keep putting vitamen a and d oitment on it and keep it clean.
