On this topic, how does being homesexual hurt? My heir was homsexual, my King dies early, like 42 yo, and so I found a homosexual wife, hoping I would not have 9-10 kids, well I still had 9 kids, and it does not seem to hurt no matter what!!!
Well, it gives -15% fertility, but since there are many traits that can increast fertility -15% isn't really that much. I remember having a homosexual heir as Byzantine Emperor and worrying that he might not produce a son, but he ended up with 7 children. What I should have been worrying about was his 4 mortal sin traits, but that was in my early days of CK2...
