So many lore retcons bother me about STD, but the multiple penis implication really irks me, because you just know for a fact that Jadzia would have alluded to it at some point given how her personality functioned. Different era and different censorship laws true, but remember the Voyager episode where Harry starts glowing after having sex with a woman? They had no problem there pointing out that she did not have the downstairs equipment that a human woman does there. And that goes double for the fact that every time we see a Klingon woman in the franchise she is either humping someone or talking about humping someone (one even thought that Neelix was a catch) and this NEVER came up? And what use would two penises be anyway? Why would that evolve?
Not buying it.

In theory it could be an evolutionary leftover that's not longer useful, but was significant previously in the evolution of the species, and doesn't significantly impact an individual's fitness to the point where losing it is significantly favoured. There's a lot of stuff like that in nature, where it's less a case of "This is beneficial" and more "This doesn't hurt me so there's no pressure to change it!"
For Earth animals with rather odd genitals, look at Echidnas, snakes and lizards (and ducks, though that's less on topic).
Following link is obviously NSFW and contains reptile penis, but the functionality explains potential uses of said odd layout:

So there are certainly lots of potential reasons.
However, and much more importantly, as you pointed out, SOMEONE would have mentioned it, and also, it adds literally nothing of use to the canon and makes conversations and whatnot that occurred in the past weird.
