Light Seeker, have you tried a schedule? Your sitch seems almost tailor made for it. You can get intimacy-that-doesn't-lead-to-sex on non-scheduled days. He should feel better providing that because he knows when he *will* be having sex.
The only caveat would be that you need to be giving on scheduled days even if you're not "into it". In other words, don't do everything grudgingly and try to get by with the minimum. He needs to accept that you'll be willing and pleasant but not necessarily overcome by desire. The idea is that the schedule allows you both to relax and hopefully your desire for sex will grow along with his desire for intimacy.
