Unconventional tribute to my husband or his sperm

Most women are freaked out by the notion of their husband donating sperm. Most wives feel like they own their husband's sperm.
I love babies, I am open to the idea of adoption. So stretch that logic a little further, I would raise children that are the spawn of my husband's sperm, regardless of the egg owner. Why is that so weird and unsavory for most people? Point of clarification for all you men reading this, it doesn't mean open marriage, I will raise the children born from artificial insemination. And to my dear husband: NO YOU CAN NOT KEEP HER IN THE BASEMENT.
