It was the early nineties, still a time of problematic depictions of consent and non-consent. In the same year that this episode aired, Robin Hood: Prince of Thieves played the Sheriff of Nottingham's forced marriage to and attempted rape of Maid Marian for laughs. In the case of a male character being coerced like in this episode, viewers of the time (and maybe many to this day) may have thought Riker should "man up," maybe going so far as thinking things like "Woooo, lucky Riker!" But with today's increased awareness of proper consent, the situation in the episode is more easily recognized as exploitative.
And there's nothing wrong with critiquing this type of thing, in both past and present media. There's a balance between dismissing something out of hand in kneejerk fashion and calling for it to be banned and whatnot; and just unquestioningly accepting the thing at face value and telling others to 'get over it.' A younger viewer attempting to approach older media without context may find many depictions to be downright horrifying, and react in the first manner while passing harsh judgment on both the product itself as well as the entire society of the time, 'throwing the baby out with the bathwater,' so to speak. Somewhere in between the two extremes, we can understand the social context that the movie or TV show, or book or song or whatever arose from in the first place, and recognize that certain aspects are not okay while still acknowledging the work's artistic merit and seeing what we can learn from it.
TCM does a good job of introducing classic movies in a way that contextualizes things that may be considered problematic today, and Leonard Maltin did something similar on DVDs of early Disney cartoons, and maybe some other movies that I can't remember at the moment.
If roles had been reversed and Data was a female-presenting android being held captive in physical restraints by a Borg "King" creepily asking her, "Are you familiar with physical forms of pleasure?," it might have raised more eyebrows. It also would have been a throwback to cheap pulp space opera from earlier decades.
