topic #31686 brought up the topic of redefining "forced" tags to mean lack of control rather than lack of consent, and creating a separate set of tags to denote lack of consent. The discussion petered out in that topic, but I'd like to forward the idea once more. This could be useful because the two scenarios are often conflated, especially in bondage scenarios, and involuntary scenarios are much easier to determine objectively (for TWYS) than consent.
To a degree we already have tags explicitly for lack of consent with the unwanted_* set of tags. forced_orgasm and involuntary_orgasm, as well as forced_to_penetrate and involuntary_penetration, are also divided between these lines. However, these tags tend to be poorly or vaguely defined.
