Is this normal or do i have some sort of complex?

Okay, ever since I could remember I've done this. It hard to explain what it is exactly, but I'll try. I know it's stupid.

I suppose one way to put it is that I try to seduce males? I don't mean it normally though. It's not really seducing, since I am extremely subtle. I just sort of open myself up more (not literally), and become more prone to affection.

The twisted part is that I usually do it to family members (not old ones or kids- gross). I really don't want them to like me. I just (not really flirt, I think) become more comfortable around them. By that, I mean I hug and play with them more.

It's like I'm testing them, though. If they do get... aroused, I guess (not really. That's too strong of a word)... I become uncomfortable and back away from them. If they remain unaffected, my opinion of them skyrockets and I do it even more (which just sets me up for failure, I know). I feel that if they really look at me like family and not a girl, then they are absolutely awesome.

Most of the time, this fails and I can tell that they see me as a girl instead of a cousin or something. The few times they pass, I feel like they're fantastic people and usually favor them over the others.

*I don't think they like me. They just see me as a girl. You know, that difference between family and friends? That's it.

I know it's stupid and pointless. It's almost as if I like the chase (though it's not really a chase). I call this a complex because I feel admittedly disappointed when they pass, and do it more. On the other hand, I become angry when they fail and back away from them. It's unfair to them (I don't treat them badly, though), and I don't want to do this anymore. What if they really, REALLY fail and become a little too aware of me? I'd hate that.

I hope it doesn't sound like I have an ego because I don't. I just thought it was the best way of putting it without half-assing it. Does anyone else do this? Do you have an idea as to why I do it?
