That being said, I'll be brutally honest. It's a personal choice thing for me, but I'm not really attracted to ladies with tons of tattoos, very large tattoos, or piercings. Maybe I'm just "old school" or something. I don't have a problem with them on my friends and acquaintances (I have many friends who have them), but I just don't find them attractive on ladies. If a lady has a very small tattoo on her ankle or something, that's OK for me, but I just don't find a lady with a "sleeve" or a "tramp stamp" attractive.
Personally, I kind of like being a nonconformist myself by NOT having a tattoo, since it seems like the vast majority of people have them nowadays. Just call me a rebel!!!
I have a couple of my own, and my idea has always been they should have meaning and express who you are rather than just be about the art.
In doing a little research on the topic after seeing this post, Leviticus 19:28 comes up often. While the verse appears to clearly forbid the practice, numerous scholars and priests (both Catholic and otherwise) say this verse was meant to seperate the people of Israel from the pagans around them in the promised land. The pagan cultures used tattoos and other bodily markings as part of worship rituals. God wanted to make sure His people were set apart.
