It's not the spunk they consider delicious; it's the spirit energy. Spunk just happens to be the most efficient way to procure said Spirit Energy normally speaking, excepting certain species that can drain it with as little as a touch or straight from the blood (see: Wight; Vampire).

And they don't have to take it in through the vagina, specifically. They pretty much just naturally absorb it through contact with said spunk in any way. Else monsters that specialize in other non-vanilla forms of sex would pretty much starve to death (see: Ghoul; Manticore).

If you read some of the other setting material, you'll see reference to plenty of non-traditional forms of sex, including bukkake, etc. If they had to absorb Spirit Energy through the vagina specifically, all that bukkake would also be off limits, as it would be wasting their food.

EDIT: Actually, there's a monster that actually might be willing to indulge in a bit of light blood-play: the Vampire. Hadn't thought of her. So I guess blood-play doesn't really fall into the off-limits extreme end of things.
