when i've been in tattoo shops glancing through the books, i had the misfortune of seeing dick tattoos. intricate detail, color, and design, and i could not imagine having that done. i'm sorry, i can handle the pain of tattooing no problem (i didn't even flinch getting the underside of my arm done) but not on my dick.
ok, i'm not superhuman with the pain, however, the underside of the arm is sensitive and it didn't bother me. my back, however, hurt like hell. but even though it hurt like hell, i managed to sit upright perfectly still the entire time. the guy tattooing me was impressed at how well i "sat." i've been told that by everyone that's tattooed me actually.
i had a friend years back that got his forearm tattooed. the design wasn't really friendly either. he told the artist "i want satan on my forearm." the guy put something really demonic on there and put a pentogram that was about 3" across in the design with only 1/4 of it covered, so you knew what it was. full color. huge piece. a few months later he said "yeah, it kinda makes family gatherings a little difficult now....." and he thought it was funny.
his next piece, however, was a wickedly demonic face on the back of his neck. the eyes were sewn shut, a small 666 on one side, pentogram on the other, upside down crosses in it, and this face, there were maggots coming out of the eyes and the mouth.....
i have to say that the detail in this piece was OUTSTANDING. it just wasn't something i think anyone should have on their body.
be selective in what you get tattooed and where you get it. i don't regret any one of my tattoos, but i can cover them up pretty easily if need be. just something to keep in mind.
