Once I met a man who had a big tattoo on the left side of his neck that said, "Pigs Suck!" Unless he always wore turtle necks while driving (unlikely in Hawaii), I imagine that type of tattoo might not go over real well with any police officers who may, some day, pull him over...
Another time, a Japanese friend and I were waiting in the check out line at WalMart when I noticed a teenage girl in front of us with a big kanji tattooed on the back of her neck. When my friend saw the girl's tattoo, his eyes got real big and he whispered into my ear that the character meant "insane" in Japanese. So, of course, I had to ask the girl about it. She explained that her nickname in English was, "Crazygirl." Apparently the girl had gone to her local tattoo parlor and asked to have a tattoo of the kanji for "crazy." She and the tattoo artist looked it up in a dictionary and then proceeded to tattoo the character they found onto the back of the girl's neck.
My friend explained to me later, that while the kanji the girl chose did mean "crazy," it was not the same nuance as in English when we sometimes refer to a person as "wild and crazy," which connotes more of a feeling of being carefree or maybe fearless. Apparently the character the girl and her tattoo artist chose meant crazy like in the sense of a disease. My Japanese friend recommended to the girl that if she ever decided to visit Japan, she might want to cover the tattoo up by letting her hair down when she went through immigration. He told her that having the kanji for "insane" tattooed on the back of her neck might adversely impact her chances for being let into the country. :)
Personally, I don't have any tattoos and don't have any inclination to ever get one, but I've seen some nice ones that I kind of liked on other people. I have to admit that when I see someone who is completely covered in tattoos I'm turned off by it, but that's just my personal preference.
OP, you should get whatever tattoos make you happy and don't worry too much about what other people think. My only recommendation is if you decide to get a tattoo put onto your body in anything other than your first language, you might want to first run it by a native speaker to make sure you don't unintentionally get something you may regret later.
