That was the impression I got, not sex but rather love.I'm not sure I buy the whole "emotional dampener came from Icheb's cortical node" theory. It occurred to me that if Icheb had such a dampener it should have gone off when he discovered he was betrayed by his parents. I mean, these are the people who are supposed to love you unconditionally. Can there be a larger betrayal?
But Seven responded to that betrayal more emotionally than Icheb did. He seemed pretty calm about the whole thing.
And Seven certainly responded emotionally many times before the emotional inhibitor was revealed. She went off half-cocked in Dark Frontier--a truly emotional response. She had a completely human emotional response to her own mortality in "Imperfection." The death of One, her feelings of remorse (expressed pretty cogently to Neelix in "Memorial")...
Perhaps the dampener was aimed toward sexual arousal rather than emotions?
She could experance emotions but not the deeper ones, like love.
I would think allowing such stronger emotions would make it easier for assimilated people to resist compling with the collective. So having an inhibitor would dull your resistance.
