Okay... but like you get the whole thing where you can't really have an informed opinion on something you didn't watch, right? You don't have to comment on things you don't want to watch or read.
I'm happy for you and your wife! Super weird projecting though, where you equate promiscuity with cheating and short term relationships. I do enjoy short term sexual relationships on occasion, so I like to make sure I'm doing the things my partners want done. After all, you never know someone's past or preferences.
No one ever said anything about getting consent to change positions and certainly not in a long term, committed relationship. They said consenting to a blowjob didn't imply consent to other sexual acts. In fact, it's in the criminal code. That's probably why the prosecutor brought it up:
Sections 276 to 276.5 of the Criminal Code govern the admission of evidence regarding a sexual assault complainant's other sexual activity. The Code makes it clear that evidence that a complainant has engaged in sexual activity is not admissible to suggest that the victim was more likely to have consented to the sexual activity which is the subject matter of the charge or that he/she is less worthy of belief.
