To add to your point, as much as I like Suzie Plakson's performance and K'Ehleyr as a character, she obtained sex from Worf under false pretenses, and then dumped him with the resulting child. This isn't something the fans like to consider, as both Plakson and K'Ehleyr are really popular among the fanbase. But it's straightforward reading of the text. K'Ehleyr knew that Worf had conditions for having sex; they had previously broken up specifically because he was not going to mate unless they first got Klingon-married. She knew this hadn't changed. Yet she was horny and wanted to get her rocks off, so she had sex with Worf anyway, then told him to pound sand when he immediately initiated the marriage rite.

If the genders were reversed, I don't think there's any real dispute that this would be treated like a sexual assault. It's sex by false pretenses. This is not a criticism of sex without marriage; what K'Ehleyr does with her private recreation time is her own business. Rather, it's a criticism of the fact that the episode specifically writes out any possible misinterpretation, or "I didn't understand" grey area. Worf was extremely clear about his boundaries, and Worf has just as much a right to set terms under which he will have sex, and have those be respected, as anybody else. And K'Ehleyr very specifically did not respect those boundaries. Yet Worf was not allowed to be mad, and was very much treated as being in the wrong and a stick-in-the-mud who doesn't appreciate K'Ehleyr. And the implication is that Worf is supposed to suck it up, because after all, K'Ehleyr is a straight-up hottie and anyone in their right mind would take that opportunity if it arose.

And then in the very next episode we see her, she shows up with a son he didn't know about, right after he's accepted a discommendation that affects the son he didn't know he had, she gets murdered, and she leaves him holding the bag. I know it should not matter, but I can't help but point out that if the genders had been reversed, and K'Ehleyr had been forced to parent a child as a result of sex by false pretenses, I can't help but think that the writers, as well as the fanbase, would have cut K'Ehleyr all kinds of slack for being a crummy, conflicted parent that they never cut Worf. Add on the fact that, yeah, Status Quo was God, and while there was certainly some light continuity within the series, the parent-child relationship was never what interested the writers, and yeah, I think Worf as a character catches a lot of undeserved flak, because the writers dropped some very critical balls in writing the character as a parent. The meta-level analysis is, I think, instructive.
