I think part of it is the outside appearance. We judge, observe, based on what we see. While that does not make a person, sometimes it is what we base perceptions off of.
When I think of the word 'butch', the way they walk come to mind. You know what I mean, right? 'The walk'. Something about it just makes my heart beat a little faster
When it comes to my partner, it's a multitude of looks, of actions, that make her butch. Does she dress masculine? Yes. From the tips of her cowboy boots to her baggy jeans, to the Skoal can in her back pocket. Button-down men's shirt with a tie, cowboy hat sitting just so. It's the way she drawls "Hey gorgeous", the way her lips turn up when she smiles at me, the smouldering look in her eyes when we make love. It's the way she wraps her arms around me when we go to bed at night, the caress of her fingertips on my face when she brushes my hair back, the way her arm encircles my waist when we are walking through a crowd. It's the loving way she brings me dinner to work, the "I love you" text messages throughout the day, the spontaneous love notes. I realize some of this do not 'mean' butch - they mean love, a partner - but it's what makes my partner 'my butch'.. so it counts, right?
