Speaking from personal experience, I've been picked up in bars by girls ONLY cuz they liked my tatoo and came over to start talking to me about it.
I've definately met WAY more girls who like tats than who don't.
However the majority like them when they are more original, uncommon, or have a specific meaning. IE - not the tribal armband on their bicep type.
Here's mine to date:
Lion Portrait (I'm a Leo)
8 months or so - Left upper arm (pic is bad cuz it was taken right after getting it by a cheap camera)
Vampiric Ankh
1.5 years old (right-side of calf on right leg)
Tribal / Flame (got this when I was 17 because I thought it'd look cool, but I don't regret it at all)
7 years old - Right forearm
