DimSum I was going to say that about the crush, but I didn't want people to get the wrong idea. But I want to say it is perfectly normal. Your a male relative she is probably close to and really cares about, she may have a crush on you, and doesn't really understand the fact that she does. That's normal she just has to learn that there are boundaries. And for me that tickling would be one of them. I love my male cousins. And I have been accused of something similar because we were home alone playing rockband. I love those boys to death! But certainly not in that way.
It could also be that she thinks of it as brotherly love, I know my brother tickles me, (and I HATE it!!!) but he's also 15 and I am 19.
