It quickly becomes very much a moral question if any of the women become pregnant.

I do realise though that you're posting in the context of a society in which the necessary causal chain between sex and pregnancy has been broken, but the moral systems we have built around sex and relationships are predicated on that link for perfectly rational and valid reasons. Also ultimately we still need people to have children and bring those children up. The moral factor in sexual behaviour can't simply be discounted.

And I'll just add that the link between sex and children is nowhere near completely severed. I am aware of tons of people who have had children A) before they planned to, and B) with someone they weren't in a serious relationship with.
