They adopt. There are plenty of children in the foster care system or orphanages depending on the country whose lives would be greatly improved if they lived with parents regardless of the combinations of genitals or gender identity of those parents.

Or those who are richer and/or in richer countries can use various artificial means.

Adoption and surrogate births. Fucking is a very small part of parenthood

I think the overwhelming majority of adopted children would disagree.

One's "real" parents aren't always one's biological parents, even outside of formal adoption (cf. plenty of Americans realizing that their older "sister" is actually their mother).

Sperm bank for women. Surrogate mothers for men.

I know several lesbians who have children.

You’d do well to not speak generally but specifically to the case. Sperm bank for women and surrogate moms are non-existent in Ghana. Take a walk on any random street and ask (1) how that woman became pregnant (2) why the child calls the parent mom or dad and you'll get traditional answers. That said, child birth/procreation isn't what the bill protects. We have no such issue in the country.

the person i answered asked a very general question.

They experiment in college

They have children with heterosexual partners. Old as world.

Let me tell you bout the birds and the bees, and the flowers and the trees.

There's also adoption.
