Well, I'm over 30... and I don't think it matters if a man has a tatoo or not.
I don't care if he does or doesn't when I meet him, because he'll probably end up with one if he stays around me long enough!!
I do tatoos, but only original artwork. No flash.
My DH has one tatoo across his shoulder blades. I drew it, I inked it. I also did my brother's arm band - just this past Wednesday. All original, all mine.
I even drew my own tatoos, but the ones on my back were inked by someone else. I did my own ankle, though.
Some people judge me, but those people aren't usually the ones I want to get to know anyway.
I say "get a tatoo if you want one, if you don't want one, that's your business... keep it your business & don't judge others with them."
(I also sew, make CP soap, teach yoga & dance, and homeschool my 2 kids... not necessarily your stereotypical tatoo artist.)
