I would be more than willing to date her. I do not feel that it is wise to play someone. that kind of messing with a person is bound to come around and bite you in the ass later in life. If given the opportunity to date such a girl, I would let it be known from the start that I hope to turn the innocents into experience. I would hope to never break the trust, and I would endeavor to show her good life can be when one succumbs to the pure bliss of sensual experiences.
If I was interested in her and was attracted to her I would date her. However, if I did not want to date her I'd most likely want to be her friend because sounds super nice and fun to hang around. Would I turn it into a friends with benefits thing depends on whether we mesh sexually, tease each other a bit, and agree to go for it.
She sounds adorable. Yes I would date her and it'll more than likely turn into a serious relationship. Just the thought of her being so trusting of others makes me want to be that much more of a better person overall. I'd love her until the day that I died, plain and simple.
