Peak, no offense taken - and with your clarification and a full night's sleep, I can better see what you're saying.
I think the difference this time, speaking for Sue, is that this was expected by her. So what I see is her compensating for the 'gap' that you perceive. You're right, and I know that she is masturbating more (I've seen evidence - her toys in different places, lubricant being used up as well as when I've heard her when she doesn't think I'm awake yet). And at least from what I can tell, her adopting the panty-denial thing again, is her way of filling in that gap and heightening her own desires and awareness of what she wants.
I suppose I could push to do more sexually with her, but I don't sense that she wants it from me. She's admitted many times that she wants another guy and I don't think that even if she and I had sex more, that it would fulfill her desires. So to your point of what Sue would like from me - that's what we've been talking about, a bit indirectly, but she's mentioned things - she again brought up her desire for an emotional affair again as well as wanting her next boyfriend to be "younger like Robert" - and the obvious desire for him to be well endowed. But other than that, I think what she is doing is merely biding our time. We are going off to ski this weekend - leaving Friday afternoon and we have other trips planned in February and into March - with her dad stabilized this year and other things being calmer - she wants to take advantage of all the exercising she's been doing and join our son and I on the slopes. I'm actually quite happy that this desire has become her focus and that Tony is "filling in the gaps" so to speak. I'll add that I'm actually a bit surprised that she hasn't spent more time with him or found more opportunities - but on the other hand, that also speaks volumes about her own self-control and self-awareness - all of which give me the confidence about what we're doing to go along with it.
Hope that explains things further.
