I was a bit pointed in my comments; not trying to put you down. But at 71, and having had a divorce practice, I have seen far more than many others.
My comment concerning children are still on point. I do not know what your phobia is concerning child birth (nor do I wish to elicit it from you), but I agree with at least one other poster, that you should do some serious work with a counselor to get to the bottom of it. And if you cannot overcome it, I would advise not marrying. It is easy to say “Yeah, I am good with not having any children” - you, or your intended. It is a whole 'nother world being married, and that has changed the perspective of many a lad and lass.
a guy could easily say “sure, no child bearing”. He may mean it; or he may be pacifying you on the matter, In either event, a few years down the road, “oooohhh, I really didn’t mean that” or “I changed my mind. Why can’t you?”
It is all nice and etc. to be “adult” and talk these things out, Surprise of surprises, men have emotions too, and the issue of having children can become a very powerful emotional force. I have seen people get divorces over far less an issue.
And none of that has a whole lot to do with what the Church says is a prerequisite for a valid marriage. As in, I am fairly familiar with tribunal applications.
