It took a while for things to get to this point and it will take a while for things to change... just try to stay focused on the goal.
Try to awaken her in ways other than in the bedroom (those rejections can be very draining and esteem crushing) by simple flirting and innocent touches. Let her know not by words but by actions that you desire her not only physically but emotionally as well. Seek her opinion on things (such as what shirt to buy) and leave her little silly notes in unexpected places. For example, leave a note someplace she will come across it but not out in the open (in the fridge, on the toothpaste tube, etc) saying something like "at this exact moment I am thinking of you".
Remember that romance starts with the mind, so engage her mind with no expectations of ML, before she can reject you, pull back. Not as if to push her away, but the moment you see her tense up simply give her a kiss and pull back.
Maybe making it a game (I will get some bashing for this one)...
No ML for two weeks, but the two of you have to tease each other silly, the winner (the person who gets the other one to 'crack' first) gets to choose the prize that is established when the two weeks start. (Such as a movie night of their choice, a dinner out of their choice or the other doing a chore they hate). We women are a competative bunch and she will probably try to win so that she can have her choice. You cannot choose ML as your prize, it would defeat the purpose, and as the SS partner you will probably lose more often than win, but she will have to work on ways to tease you to win, and in doing so will find the fun in being sexy.
