I have noticed that tall women, or any woman for that matter will not date someone shorter than they are. I like tall women, but am only 5' 9", so have never been able to date someone taller than me. Of course, I am no longer looking.
I'm probably the exception among women in that I like short partners. I want to be bigger than my lover, not just in weight but in height as well. Large and in charge!
Now, height isn't a dealbreaker for me. I'd happily accept a tall FA or feeder who otherwise fit well with me. But ideally I would like a lover who is noticeably shorter and thinner than me.
