Christ, this is an old post, but I have to stick an oar in on the accuracy front...
Five *tablespoons* as an average serving size of semen??? Are you playing with some other species? Bulls, or horses maybe? Or are we talking full-on bukkake parties?

Human males ejaculate roughly five millilitres - about one teaspoonful of semen at a time (it looks more sometimes because it sure spreads a long way, but try pouring out a used condom sometime, if you want to test it). Most of this is water, salt, a little protein, very little fat.

On the other hand I think the details of the composition are about right: if you correct for the actual 'serving size' you get just under 1g of fat per orgasm. That doesn't sound too off-the-wall.

Or are you deliberately misinforming these poor girls because you disapprove of teenage anorexic blowjob-givers?
