Dave,
If she doesn't "get going" until after you start, then I can certainly see how that would prevent her from pulling off a killer initiation. She can, however, do better than what she's done lately right!

Here is my question for you: Are you proficient at getting her going, once you start? Do you know her preferences? Does she?

If she has trouble getting started, then it might benefit the both of you to move that along in a way that really speaks to her.

I truly do empathize with my H for being in a position where he is expected to deliver the goods twice per week, but less natural desire than that..it leaves him in a position of either faking his desire (which he does quite frequently) or borrowing mine (which he attempts to do frequently). It is my hope that I can help with this process by getting him in the mood in the way that HE suggested so that his desire won't be either faked or borrowed.

just some thoughts for ya..
