Do men enjoy watching women stretch at the gym? If so, why?

I work out at a gym where I have begun to notice one particular guy make his way the water fountain a bit while I am in the stretching area. We (the gentleman and I) have made eye contact in the past but no words. I think he is really cute but he has never said anything to me. I have also noticed men looking in my direction when I stretch sometimes as well. Mind you I do not dress like a "skank" nor do I show myself in a way that would imply "" intentions towards anyone. I just do standard stretching; ones that I have been taught to me by instructors.
