At some point in most women's life they will want to have children. In some cases this will be after marriage and a home has been set up, for some it will come later and for some the desire will be for a child and not necessarily a husband.
Children will make most people happy, and even troublesome teenagers will create more happiness than sadness. However life with children is considerably more enjoyable when you have someone to share all the best moments with, share experiences and milestones, and help in their care. Traditionally this has been a male female pair and does have some benefits for the child in seeing male and female roles. However a happy and loving relationship is more important than a opposite sex pairing.
What we would say is that you should have children when you want them, and under whatever arrangement that you wish, so if three women sharing a house and living as a unit is ideal to you, where you can over the years take turns in staying at home and taking care of childcare while yours is the smallest child, then that is fine, as is the decision to become single mother who either works or does not. If your only requirement for a man is to conceive then borrow one when required. Likewise if you are not expecting any relationship with a man to be permanent why not select the ideal man as the father, even if you are not ever going to live with him. Of course many women do this now secretly within marriage, as a natural way to increase the abilities of the child.
Children can make you happy, but you will be happiest if you have them when and under whatever arrangement you want to, so don't bend on this to suit the will of other people.
