I don't think the Hirogen were thinking about sex within the holographic simulation of WW2 at all, they were all about the glorious "Hunt". So no, I don't think there was any actual pimping or copulation going on. Even B'Elanna's pragnancy was only a simulation to inhance the hunt. It isn't called "Killing Game" for nothing.
But they've got all the WWII info out of VOY's databanks.. surely there's more sociological tidbits in it than Neelix having baguettes.
