YES - rip the buzzer out of her hand. Even if it's the *wrong* move or not what she wanted or had in mind, do it do it do it. Make a move, so she can react, so you can learn what she wants. If you always ask first or stay paralyzed in fear of making the wrong move, you'll never give her what she wants and you'll never get what you want.
She doesn't know how to talk to you about this. The pat on the head is an indication that she thinks you are a really sweet guy but she needs a pirate/caveman in the bedroom.
She probably feels that telling you how she wants it is just leading you along so you don't have to initiate and be brave. Turn off.
Her laying naked for her massage with the buzzer. That is HER initiating. You might have secretly hoped that the massage would lead to something without you having to blatantly initiate. Don't use massage as a sneaky way of trying to initiate. She knows that, by the way, and it's not doing it for her.
Burt - Initiate and be brave. If at any given moment you have an idea that you want to grab her, grab her. Even if it isn't the right moment for her, she'll LOVE that you found your manly man.
In my perspective, a man who can initiate blatantly, with confidence, is a huge turn on.
You need to do this without a cue like almond oil or music (the cue that my sister's exBF used to use). Cues make a girl roll her eyes. "Oh boy, I guess he's putting his pinky toe in the water. My hero."
I'm just realizing that I'm as afraid to hurt you as I am afraid to hurt my H. This exchange is important to me, too.
