My ex girlfriend told me this several times. It was particularly attached to some of my mannerisms. For instance when we were cuddling I would often rest my head on her chest and shoulder or sometimes on her lap. Or I would be the one being held instead of holding her. She would usually tolerate this for awhile and then say angrily to me "I wanna be the lady!" and switch positions to a more traditional (and more comfortable for her) cuddling pose.
