Senseless attraction

So I saw this person today, who I used to be really attracted to. As in pure, unadulterated desire. At the time, I thought he might become a challenge, and even possible fall, of any other relationships, as I would never be able to say no to him. That changed. He, umm... turned out to be a lot more talk than action, and not living the talk. Failing to live up to his words, I realised that I wouldn't play his game. If he wants me, he'd better let me know and come clean about things. I need to protect myself.

And seeing that he's a man, and I prefer women, I thought I was well and truly over him. Until now, when I realise that the same desire is there, even though I'm still as annoyed with his manboyish lack of responsibility and still don't want him in my life. Emotionally, I don't want him. But my body betrays me. So the risk of him jeopardising relationships is apparently still there. But I dare say that it's a challenge I would win.

Do you have people who attract you in the same senseless way?
