Didn't know you was 18, LOL. And, hey, you never know... My younger brother's first wife got one on her butt when she was 31. And showed me. Somehow, I never knew just what she'd gotten tattooed...
I regret all 3 of my tattoos. The 2 on my arm are just dumb, in hindsight, and the one on my chest would've been awesome if the tattooist had done it right. I've never had the money to get it fixed.
