lol genius. Is that a background character or someone actually important? It could always be argued that they're in a relationship already, and don't forget Vorik chose Torres because she was what he considered a good mate, not just a handy female nearby.
As for them discussing it. Vorik and Tuvok go out of their way to not discuss it with the EMH, Tom's clearly never heard of it until Tuvok has to explain it. There's also the scene with Tuvok in Vorik's quarters, neither of them look particularly comfortable talking about it. I get the impression for Vulcaons it's become "Come home, get your end away, and leave. Let's never speak of this again!"
