I have always liked mostly "boy" things. I love power tools, woodworking, taking things apart...that kind of stuff. However, when I was little I also loved dolls and dress-up.
Now, it may be different because I'm gay. I find very little use for what most straight women find important or interesting. I'm also far more logical than many straight women I know (as opposed to being emotional, but then I'm an aspie, so?).
I know of many girls and guys who are into dragons, for example, so not something I can comment on.
