Opening up lines of comunication can be very dificault. I under stand your delema. You love him and do not want to have him think badly of you by these desires. What I would recomend is a weekend alone together. If you have kids find a sitter go to a hotel. Have some intimet time together. Just talk, ask him what he whould want. You may find that his feelings are not that far from your own. I think most men would love to just through there mate over the couch and do her like a big dog. But he has the same problem that you do and that is Fear:

Fear of what he will think
Fear of what he would say
Fear that he may not love you any more
Fear that he is disapointed in you.

I am sure that he has the same fears as you do.
Good luck and hope you get some time together soon.
