Muldoon is not worrying about Midge finding him unattractive at this stage. He's certain she will tell him one way or another if there's something she doesn't like. She's outspoken like that, and he appreciates it.

Instead he's focused on, as they said earlier, making the most of the time they have. As soon as the door is closed, he cups her face in his hands and kisses her. Deep, careful kisses as he walks her backwards to push her against a wall so that she doesn't have to worry about keeping her balance as they get to know each other better.
