Should I Feel Bad?

We have been having meetings at work, with the CEO, financial directors, and even the Board.
The CEO is a great guy and very down to earth. I have not once had a problem with him. He treats me with respect and introduces me to others with the highest regards. Several other people have made comments that he is old-fashioned and does not want to see women succeed or work in management roles. I don't see that, but I guess we are all equal. I have never got that feeling from him. I am not afraid to say Hi to him as I pass him or even laugh with him. He does not act like he is above the rest of us, so I don't feel intimidated by him. Should I? A lot of the women around me seem to keep their distance from him, because of his position within the company. He approaches me and talks to me. He jokes with me and laughs with me. He acts like I'm a human. Is that wrong?
