I realized in the 1960's that one way to not have children in this violent world was to be gay. I realized that a lot of folks thought that way. If you did not get pregnant then the world population would not increase. A lot of folks have made that choice.
When I married I did not want children because I did not want children growing up on a violent planet. Laurel Rose's choice was to have children. I have no regrets and I changed my point of view. But I still understood why some folks became gay.
