Depending on the size of your wedding and how much work you will be doing…well, let’s just say that most couples with whom I have had an occasion to speak with about this who have already been having sex, basically said they were too exhausted on the night to do very much at all.
But that’s up to you. May I ask why you would think to do such a thing? And if you were going to do such a thing, are you going to cut off everything? I could see it being kind of fun if you allowed yourself to neck and nuzzle and make out but no actual sexual contact, to build the desire.
Besides all that, I would discuss it with him. “Cutting him off” sounds extraordinarily negative; aren’t you cutting yourself off, too? If both of you are amenable, it’s just a month, so it might be fun. If if really is YOU making a sexual decision for both partners, then I’m sorry, I can’t get behind that.
