OK, here's what I'd do:
- Rest up, both of you, and try and take some time away like Friendowl suggested so you can focus on each other
- Talk about the fact that you'd like to work on upping the intimacy but leave out the part about him not doing it for you (that is a drag, though)
- Ask him if y'all can try and take a stab at reinventing your sex life and diplomatically tell him that you want to spice things up
- Introduce some pretty underwear, toys, or other props if they'll help. Do yourself in front of him (that always lights my husband's fire in a big way) or have him watch you so he can pick up your technique, if his is lacking
- Seduce, seduce, seduce. Even if I'm not in the mood, if I work on getting him in the mood or trying to distract him, it always gets me going. You know how to do this, I know
- Keep working on that bond in other ways because if there's some other area of hesitation, anger, or hesitancy, that'll definitely get in the way in the bedroom. Are you harboring anger or resentment over anything on some level? Is he "doing it for you" emotionally, spiritually, intellectually, too?

My heart aches for you that the attraction factor isn't there because it definitely helps make everything else easier and keeps the passion as a solid baseline when other areas of the relationship are shaky or you're going through a rough patch. Are you wary of counseling because you know you'll be forced to deal with the fact that the truth is you married a man you're not terribly attracted to? On some level, I expect he already knows that that's what's up, don't you? I can't imagine your being married to someone who's not fairly sharp and perceptive.

Above all, do everything you can to work on the whole bond between the two of you, Demeter, and get it strengthened up now. Sex is a barometer of that bond, and if things are shaky in that area, there may be little fault lines in others. I recommend working on strengthening the bond ASAP because when you two bring those girls home and you suddenly find yourselves as new parents together, you're going to face a whole new set of challenges to that bond, and you're going to need as solid of a foundation as possible, both to weather the storms of parenthood and to have that bond in place for the security of the children. Kids, interestingly enough, have a relationship with their parents as individuals but also with the marriage itself. And so presenting a solid front of intimacy is not only important for you two so you can stay together to help raise those kids but also so the kids will have a good model for their future intimate relationships.

Hope that made sense. I wish you the very best of luck with this, my sweet, creative friend.
