I'm not a big fan of tattoos or toe rings for that matter!
The purpose of a tattoo is to draw attention when exposed.
I suppose a small one isn't as bad as a large one but given a choice dating two equally attractive women with one having a tattoo and the other without one .... I'd go with the one without a tattoo.
Bottom line though it shouldn't matter what a guy thinks. You want to be loved for YOU and if having tatts is a woman's thing I'm certain there are plenty of men who'll love them !
