[In all honesty, Karna never actually had interest in taking the crown in the first place. Position of power wasn't really something that he cared for. He didn't earn it through hard work but by convenience of being his mother's son.]

I can appreciate the beauty of others.... [It's not quite the same to be interested in them though. He wonders if the other realizes what he meant.]

I would assume that the lack of experience may be a problem. [He had never looked at someone and been tempted by such passions. Or perhaps he had never thought too much to look at someone in that way.]

I lack the experience of being intimate with others.
