I'm not asking the dev to put it in, it's their game (I'd prefer it because it is a kink of mine, and part of the appeal of a harem to me is the horde of kiddos with a huge inbuilt support network) but per the lore I just assumed he couldn't have an heir, not that he was expected to never procreate, it's entirely possible I've misunderstood that.
I pretty much only chimed in because no more fucking after impregnation was such a wildly out of left field take for me.
I get if it's not someone's kink, but being surprised that is a kink at all seems, strangely naive to me.
One can enjoy sex for pleasure and procreation, without being part of some fringe religious belief.
