Age creeps up on us and it not always a question of feeling old ( but it can be.) It’s more about life stages and when we want to or are ready for certain things.
Look at it this way. Some women don’t want children, ever. Some have them early and some have them late. But as I face 40, do I want a newborn child accompanying me through my 50s or do I want to be traveling the world?

Questions without answers. This sort of question is really a two person question. You do need to consult the Penis in your life. If you feel you don’t want to discuss it with the Penis then you have a problem. Yeah yeah it’s ultimately your decision because you may end up alone with what he will view as his mistake but a child deserves you to make a good choice of husband who is not just a sperm donor.
When considering a child think long term. Think spotty teenager in a bad mood for 3-5 years who calls you their ATM. Think about what sort of role model you are. (Wish someone had told me that earlier. )
Just remember that once you have a child, your life is no longer your own.
