the more I think about , the less likely I think it is. I googled "DIY insemination" and some of the sites do explain how it's done, but it's based on doing it within half an hour of ejaculation.

At the risk of sounding REALLY unromantic about all of this, I wonder how bull sperm is transported for cow insemination?? Dont they sometimes send/receive between states?

Maybe we should just go on a BDing holiday, haha ...
