People always say what a waste because there won't be biological children but that won't always be the case. (To pass down good looking genes) Besides I think it's an even bigger waste to pass up an opportunity to adopt a child who needs a good home.
I cant even blame that lady forvwhat she said cos I feel the exact same way about good looking/really nice/sexy heterosexual men, or as I like to call them "a Waste of Resources" cos they're just THERE but I can't even shoot my shot with with them.
I think the lady meant what a waste for the ladies that would like him, 'cause they can't date him or anything lol. As in it's a waste from the perspective of a heterosexual lady ._. I really don't think she meant about passing down genes or w.e.
