[OPEN] Sexual Orientation doesn't effect Wants

I have all expacs if thats relevant info, and no mods or CC.

My sims are both male, one of them cannot get pregnant and cannot impregnate, the other can only impregnate. They both frequently get the ‘try for baby’ want with regards to each other. That isn’t even an option for them to attempt. Is there something I can do to stop this? Do I need to make the other sim infertile as well?

Thanks!
