I am going to go in a little bit a different direction with this.

Barn have you ever indicated that things like that morning wood and so forth have anything to do with ng and that you are actually in a sexual mood for her?

My meaning most males I have known wake up with that down to my sons even in there infantial stages. As female you get as use to seeing your mate in that state in the mornings as a male is waking up with it.
Alot of males say it is not even a sexual thing but with stroking it it can take them to a sexual aroused state. So how is ng suppose to define the mornings when it is just a morning woodie or out of desire/true want to have sex with her? Do you give little indicators to her so she can know you are hot for her or do you just want her to take on a feel test every morning to gauge your reaction.

With my H it is fairly easy to tell. If he gets up and pees and it is gone it was not he was aroused for me/sex. If he gets up and pees and its still there when he comes back to bed or returns quickly well then it is about wanting me/sex.
But usually he will let me know in other ways also. Leaving the guessing game out of it.

I also wonder just what it is that ng could due to show you she desires to have sex with you. What in your minds eye you would see as indicators that she truely wants you.
Is it braizen actions and words you want instead of the more mild actions or words.
I want you to do this to me right now vs well if you want to do this to me sometime that would be okay type of talk or actions that you are seeking. I can understand that. A show of impending need now not a forthought for future times.
Example
If my H was to say to me. Gosh right now I would really like to have sex with you and do it from behind. I would could find that hot. Over a statement of sometime when we have sex I would like to do it from behind. Both show he is thinking about sex and what he would like to do but the first shows a stronger need and desire with a burning need/urgency behind it. The second statement is to timid to be hot IMO.

I have seen a lot of people speak of wanting to know there spouses to desire them. And often wonder if that lack of urgency and show of immediate uncontrollable soul defining need is what they are longing to see in there spouse.
So I thought I would put it out there.
