How do you make someone feel something they don't? Is it enough if they fake the passion? But really - its not that hard for us to know to know if they are faking it.
Now my H is usually very passionate once he gets going. Its luring him into the sack that is a problem
To get back to my point - let me give you an example. While I am very much a HDW, my desire level took a dive for the first six months after both D3 and S0.5(how do you say this for a 7month old, btw) were born, because I was breastfeeding exclusively. I am still nursing my wee one, but since he is on other foods, I guess the hormones are coming back to normal and as my H put it, "I am back". Anyway, the point of this story is that from Jan-June of this year, I was pretty much ND. It was a revelation. While I normally have sexual thoughts a few times a day, and sometimes even a few times an hour, during these 6 months, days would go by and it wouldn't even cross my mind. If my H were clamoring for me to show desire and passion, I would have been quite lost.
This is something I am trying to come to grips with. If H does feel this way, then it is unfair to expect him to show feelings that simply don't exist. Then Michele is right about the desire following arousal, and 'Just do it' makes sense. Then it seems a schedule, or atleast a loose schedule, is the best option.
