That so anecdotal. It could be a lot of things. Just from talking with female aquantences of mine, I know they first and formost dont like a cocky attitude. Secondly how you carry yourself is important. For the ones that dont mind a guy with muscle, they dislike a guy that walks around with his arms flaired out like he has the worlds biggest lats. Wearing a wife-beater or your little sisters t-shirts everywhere is also frowned upon. But thats just the Bitches I know.
