Maybe you are just attracted to ladies who are open to exploring relationship configurations and physical/visual presentaions that are outside of the hetero-normative models we see in more mainstream culture. in other words, perhaps you like free thinkers who don't allow themselves to be confined by social norms and perhaps these visual gender cues are giving you reason to believe the ladies might be similarly nonconformist and exploratory in other areas of their lives too. That's my two cents anyway. :)
