I don't have a problem with tattoos or body modification. Was in my late teens/early 20s when the whole body modification movement started to gain traction/wide exception. I have gotten 2 piercings, left ear. 1st one was fine, had no problems with it, other than hiding it while it healed (active duty AF). 2nd one the asshole went through the cartiledge of my ear lobe instead of just the loose skin and it never took because I couldn't keep the training ring in 24/7 being on active duty. It eventually healed, but the piercing failed, thank god it never got infected.
I rarely wear an ear ring any more. I'm bald, with a goatee and don't want to complete the pirate outfit.
I've always toyed with getting a tattoo but never did. I knew I didn't want to get one in drunken stupor. Was hesitant also because I wondered how it would look 20 years later on my fat wrinkled ass. The more education I got, the more I worried about gettting hepatitis from it. At this point in my life it's pretty much an after thought. If I did it would probably be a Blackhawk themed tatt in some way; 4 feathers, the indian head, tomahawk ect...
Would agree if your going to do something like that you should put some serious thought into it before hand. I would never allow my teens to do anything like that (well a single non-visible, non-oral piercing or ear piercing would probably be okay, but definately no oral piercings, nose piercing or tatts). Once their 18 I would hope they would make thoughtful intelligent decisions about it.
The one body modification that drives me crazy is the earplug/expander the stetches the ear lobe until you have huge loops of stretched skin. That just looks fucking ridiculous on a 22 year old white spoiled kid from suburbia.
I also don't get the lumps, bumps, spikes, split tongues, horns ect... that people are getting, but if they are adults and that's what they want so be it.
I do think people should consider the medical risks before getting significant piercings or tatts. Those buisnesses are regulated very differently state to state from a medical stand point. Some states have very strict over sight, others don't. I would want to make sure the "artist" has a good reputation, appropriate training, proper license/certification and practices his profession using sterile technique, sterile equipment, fresh sterile ink for each patron ect... A nice tatt is cool, living with chronic hepatitis C is un-cool
