I saw. You said "never explicitly addressed." For that to be more than just making something up, it has to be there at least implicitly. It wasn't, because in fact Jadzia
explicitly stated why she was ashamed, it was because of Curzon's indiscretions [

DAX: I won't discuss it with you. As for Enina Tandro, yes, I feel the shame of Curzon's indiscretions. When one of my kind stumbles, Benjamin, it is a mistake that's there forever. I can't tell you which part of Curzon Dax couldn't stop himself from acting shamefully with another man's wife. I can tell you that he did love her, for whatever that's worth.
See, I too can use the word
explicitly. I already said what I think of being adulterous. It's not an exclusively masculine trait; it's equally feminine.
