Childless couples, those who can’t afford the grueling process of medical assisted parenthood, single people, who remain so for one reason or another..not always homosexuality, often need an outlet for the very real need of someone, something to care for, someone or something to love beyond themselves.
I do not judge them harshly at all.
I think if one is short a friend or something/someone to care for, they can find plenty to do at a retirement home or Veterans hospital. Animals are lovely, but shouldn’t be a substitute for another human being, only a plus.
