BBM. This is not the case. There is safe, legal BDSM and other ways to express lack of consent like verbally with a safe word or physically by fighting back, rolling off the person, etc. Consent, in general is the clear presence of "yes", not the absence of "no". In this particular case, yes I believe BB is screwed, but that is because of the threat of extortion and coercion. When I said "manipulation" I meant grooming, large age gaps brought on by violent individuals seeking that out and general predatory behavior, which I believe all fall under the category of sexual abuse - along with r*pe and other nonconsensual sexual behaviors.
IANAL, but if the moral of "don't have dirty sex in UT" actually comes up and this case turns to precedent on a blanket ban on certain sexual preferences/practices that are not *actually* illegal in nature when engaged in by consenting adults, this could turn into a major political, religious and moral battleground. The state of Utah has to be really, really careful on how they prosecute this case because like it or not, there are safe, healthy and currently legal ways to consent to many kink and fetish sexual practices, and interpreting the law in the way you imply may turn into government overreach instead of actually punishing predators, which is the likely intention here and could possibly punish federally protected groups.
