That is not entirely correct. The vulva is the outer part of female genitals. It consists of the clitoris, clitoral hood, inner and outer labia, and the vaginal opening. I have all of these, but a vagina as well. That is the receptacle for the penis. Where a fetus gestates is in the uterus. The uterus is what the Bible describes as the womb. Sperm deposited in the vagina migrates into the uterus and fertilizes an egg, which then begins to grow there. I do not have a uterus, but I asked my surgeon about this. They are experimenting with uterine transplants, and they have become quite successful. With a uterus and a set of ovaries I could be a fully functional fertile woman and get pregnant and bear a child. When I asked my surgeon about this, she said we are very close. I suspect in the not too distant future you will see a trans woman get impregnated the normal way and have a baby. That will turn the arguments of the trans phobic community upside down.
In the meantime, I have to be satisfied with a fully functional sexually responsive vagina. I am no different than any postmenopausal woman or one who is infertile or has had a hysterectomy. They can’t bear children either, but can engage in sexual activity and enjoy it. The lack of a uterus does not make me any less female.
