Thing is, semen changes pretty fast due to enzymes and goes from acidic to very alkaline once the different nectars, saps and juices mix. The end result within a few minutes goes from a shimmering man-hot load with complex textures and subtle tastes to a runny and clotted mess that's taste is completely overwhelmed by alkaline astringency, so I can't see how ice...um..semen-cubes could work (unless you can flash-freeze it). The pizza thing sounds more fetishistic than flavour enhancing. Not that there is anything wrong with that.
Now, I can see having oysters or sashimi and some stud does an erotic dance where he undresses, starts to stroke his cock. The dance climaxes with the dancer lying down on the table and the sashimi is quickly laid out on his chest and stomach while he works up a huge charge (maybe even help him!) of an orgasm, shooting his gleaming seed on the oysters or sashimi or plain rice balls, fresh from the source and still alive!. Eat right off his chest and stomach (which is regularly done with women) Eat with gusto, as it is very perishable.
But I've gotta say, I prefer my semen like my Scotch: Neat. But like my cream: Fresh.
