I wouldn't listen to anyone shooting down the idea of you producing biological children. Reproduction is a basic human right and you are entitled to its pursuit as much as any other human being. It is one of our most fundamental acts as forms of life and no amount of labels or aspersions will ever be able to deny you that truth.
As for the role of parenting itself, I believe the most valuable parent a child can have is simply stable, patient, attentive, and caring. Although the act of fertilizing an egg is technically "fathering," you don't need to be considered your child's father with proper planning (unless you would like to be). Many children have two mothers. If you are more interested in a male partner, then there are also trans women out there who have had their child born through a surrogate mother, and the male partner adopts the child as his or her father. If you prefer to remain single, then the surrogacy option is open for that, too.
Parenthood is powerfully influenced by proper planning. Whatever label or route you choose, I feel that your ultimate goal is simply to love, protect, and nurture the child, and any role is capable of doing that as long as the right person is in the position.
Although I have no intentions of having children myself, I can empathize with the inability to give birth causing frustration. It is one of the main reasons that I made my decision to remain childless. Despite that, I find it very important to encourage you towards parenthood regardless of your means of reproduction -- if that is truly what you want to do with your life. I really feel that is a decision that belongs to you and no one else, and that there are many options available to you that allow you to compromise little of your own dignity or desires. I really wish you the best, Elsa.
Edit: I wrote the wrong name!
