Time for a woman's opinion. I have 2 tats that I got this year - I'm 41, so I thought seriously about this. Personally, I think all tats should be able to be hidden when the occassion calls for it. But I appreciate a truly artistic tattoo regardless of the location on the body or gender of the person. If the person is sexy and the tat is well-done, it adds to their sexiness.
I also feel that since you're getting something that you'll have for the rest of your life, you should get something meaningful. Getting one just because your friends have one is just as silly as anything done due to peer pressure.
Mine both have very specific and personal meanings. They're on the tops of my feet so they can be easily covered if necessary. One thing for everyone to remember is that with time, comes the ravages of gravity. That great tat on your hip or back looks fabulous when you're 25, but at 50, not so much.
