I think having a child, or not, is the right of any individual - subject to nature's gifts being awarded or witheld.
The wording of your initial statement is interesting. It infers that you think that men have a 'right' to have a child, but they are being difficult by witholding it unti later life, or choosing not to 'bestow' the gift to a woman at all.
Your second statement indicates that you are with a partner who does not share your wish for a child.
Whereas i feel total sympathy for your position, I don't think you can blame your partner for 'witholding', and thus denying your 'right' to a child.
I believe that children are not a right, they are a gift, and it is not for everyone to be blessed with that gift, for a variety of reasons.
If it is so important to you that you have a child, then you must discuss this in great depth with your partner, and if you feel that your relationship hinges on this aspect, then you must consider finding another partner who sees the concept of chilren and childbirth in the same way that you do.
I wish you happiness and fulfillment. and that you are able to have a child you obviously want, but I think that blaming a partner for 'witholding' a child from you will only bring you bitterness and regret.
The choice to bear a child, or not, is ultimately the choice for a woman to make, but to partner a woman in conception is ultimately the choice for a man to make.
I know this may not be what you want to hear, but I hope you will give my post some thought, and some talkng with your partner.
I wish you well, which ever way your future takes you both.
