I found that something that really helps me to get my thoughts out is to keep a journal, because I can release my thoughts w/o interuption or distraction that can come from a spoken conversation. Maybe sharing your written thoughts with your husband will help? And then you can discuss afterward? I think it is wonderful that you desire to be so open w/ him. Good luck finding the medium that works best for both of you.
Sex between a man and a woman can be absolutely wonderful - provided you get between the right man and the right woman. ~Woody Allen
