Talk to him about your stuttering. This is something you need to do. It took me a year to tell my girlfriend and when I did she smiled and said "why did you wait so long to talk to me about it?" And gave me a hug. Your husband loves you and knows you stutter, and probably wants to talk about it too. Life is SO much easier when you stop being ashamed of your speech and just be open about it. People are generally very empathetic and it clears up a lot of awkwardness.
