Prudence, you've published letters from apparently oversexed males before, but you never mention their age, whether because they didn't say or you chose to leave it out. I know this will sound politically incorrect, but for Pete's sake you're a woman, and maybe this is why you don't touch upon this, failing to allow for its import.

Males in their late teens and early twenties are usually more sexually driven than their age-comparable lovers; to some extent this is NORMAL. If, on the other hand, 'horndog' is 35 plus, I would be surprised by his appetite.

One imagines he's already jerking off a lot before you advised him thusly, but didn't specify this out of embarrassment at being so specific.

Apart from eating a lot of fried food so as to accelerate the limping effect of time, it sounds like Horndog needs to find more non ejaculation-related activities to occupy his day and tire him, like joining some kind of intramural sports league(Maybe a fencing club? Sorry.).

As far as the dietary option, needless to say it's ill-advised for more reasons than I can list within the Fray word limit, so I wont.
