Do I look like like a play doll, a one night stand, or intimidating?

I'm almost 33, seeking to date or get into a serious relationship. Currently it looks like I only seem to attract men who are unavailable and seeking an extra trill in their lives, also older guys tend to approach me. It annoys me, I don't believe am giving out the wrong signs to these particular men. However the men that are umed available do not (very seldom) approach me, what am I doing wrong? I've been told in the past that I'm intimidating, which I don't think I am, yet my sister just stated a few days ago, that I am a strong independent woman, who knows what she wants, and that energy might project intimidation amongst some men. A little about myself that may help your answer, I'm hard working, and while doing this working on my second Masters, I'm a social person, but don't get around to it as much do to work, I love traveling and new ventures. When it comes to men race is not an issue. I love tall me 5'10" /6' and above, but it's not a priority... any suggestions?
