It really depends on her intelligence and the rest of her character. Some experiences in life forge your character so that you can be more wise and caring.
Innocence is attractive to me because then the woman seems more approachable. I was fairly sheltered growing up (but not totally). It is really nice to talk with women like that - however, I would be concerned with corrupting her. Sometimes when she doesn't get some slang that most of us take for granted it can get a little awkward

. At the same time there is general concern, as people prey on it. But innocence is a rare treasure these days - it will be lost, it depends who you lose it to. Someone who loves you and teaches you the easy way, or someone who takes advatage of you and hurts you in the process.
