Uhm. The stomach can hold 2-4 liters of fluid. Each ejaculation is about a table spoon. That's 133-266 ejaculations. If it takes him at least one minute to 'service' someone then his stomach would have enough time to digest any semen before it got anywhere near that amount assuming you could find that many men for it in the first place. Oh, and you'd throw up if your stomach got too full. They don't do a stomach lavage because you ate too much, they use it for drug overdoses and such.
I stopped reading after the first paragraph. Poorly written "entertainment news," with no journalistic value, and too crass to be taken for humor, if it's a joke.
Agreed, I don't find this funny at all - I've had family members have their stomach pumped after swallowing lots of medication, and it's not fun for anyone.
