We're all secretly envious of your spouse. Can you hear everyone here cheering you on? Good. Remember, its not the act itself but the desire that we so crave.
How to "just do it"? Well you could start by giving him passionate kisses instead of just those oh so quick pecks on the cheeks or lips whenever you get the chance (not all of your actions need lead to LM). Send him sexy email, leave little love notes or call him in the middle of his day just because. He will love it.
I don't know how long you have had SSM in your M but my bet is that if it has been this way for a long time, then he not admitting his real feelings to you.
Do try to keep up with what you are doing now. You need not necessarily discuss it with him as it will only provide pressure for yourself and as for your H he may be too afraid to hope for change only to be let down that is if you get his expectations up. Just try your best to keep doing what you are doing and observe the changes in him. Read up as much as you can and do follow the HDH's threads. It will give you a real good inkling about whats going on in your Hs mind. Oh and do keep us posted as we will undoubtedly follow your thread to see how you are progressing. Good luck. LH
