Klingon culture is sexist. Probably a hair less sexist than modern human culture.
Worf, individually I would not consider sexist. All of Worf's romantic interests are people who are emotionally above him and he respects. He believes that the personality of the average woman has different characteristics than the personality of the average man, but that's not sexist as long as it doesn't cause negative behavior toward women who don't conform to that 'Average'.
