Should I date my friend to see what happens?

I have a good guy friend that I hang with often, I trust him and find him sweet and dependable, but for some reason isn’t my type. I don’t know why really… maybe it’s the lack of physical? Or I’m looking for a different type of personality?

He said he likes being around me and has coyly suggested we try being together, but I don’t want his feelings to get hurt… I feel like I’d be using him, plus I think I’m interested in someone else but I don’t think they’re interested in me.

A friend once told me that I need to stop worrying about others and think about what I want, but it’s all so confusing.
