I'm trying to act like a gentleman, but am I missing sexual cues?

Multiple times over the recent past, I've had incidental contact with attractive women that seemed to be ok with them, but in the interest of seeming like gentleman, I moved away.
-At a sporting event, I watched our knees get closer together until they touched, then *I* pulled away.
-Grabbing something from my bag, I had to pretzel around her although she could have waited for me. This led to a little incidental crotch-ass contact which didn't cause any recoil.(Later, she suggested we share a snack, which was also interesting.)
-She stood close to me at a gathering, at two different points--within my personal bubble for sure. When we inevitably brushed arms, she didn't pull away. I held out for a few beats before moving.
In each case, I didn't want to make them feel like I was trying to dominate their space, but I kind of sensed that they maybe didn't mind. Is it likely they found this incidental contact fun? Arousing?
