Here is my view from the other side, I have a cousin 1 year older than me and he seems to like me, he will lay his head on my stomach or legs, and I'm ok with it, I kinda wanna kiss him, but we are rarely alone and when we are I feel strange. When we are alone we are always camping so we are laying on his bed and my other cousin is there too. I told her about it and she said it's just because he is a teenage boy... Everyone feels this way and I am currently debating on weather I want to actually kiss him. But that would make it awkward. I know that I actually like a boy and I don't like my cousin. But I still want to kiss him. I think if anyone has a cousin that they are close to and close to the same age then they will feel this way. So try to kiss her if you really want but if ur not sure then find someone else, everyone finds someone they are attracted to. (In this sense not ur cuz) hope this helps
