I have a friend who is having similar thoughts atm. It never even crossed my mind but I think if it had DH would have been very upset at the thought of me not letting him see his child being born. You should talk to him, from what I can gather, seeing a women give birth leaves most men with an amazing new respect for them. They see the strength the women have and get to witness something that they have always taken for granted (the whole pregnancy thing).
I def think that you should talk to him. Hope it goes well
