I never did understand the Worf/Troi thing. Worf likes it when his women get aggressive. Troi is anything but aggressive.
I never did either. He sure seemed to "warm up" to the aggressive display that K'Ehleyr put on. But maybe the other Klingons were right. Over time, Worf became more humanized and found Troi's softness exciting (it was near the end of TNG anyway).
