I am happily married, and he is a great lover, but I do like some 'play' that he does not.  I like playing the part of a sub and I want him to play the Dom part, but he just doesn't get into it.  He will tie me up occasionally---I love that part, and I've talked him into spanking me, BUT he will only give me a few swats and he stops, he is afraid he will hurt me.  I told him that we have a 'safe word' and if the pain gets to be too much I'll use it.  But he always stops after a few swats, he says that my butt was getting too red.  This drives me crazy because I'm dying for a good hard spanking.   Is there anyway I can get him into being more of a Dom with me?
