No one cares. Why women allow themselves to be filmed during sex is beyond me, as they invariably are released. That said, no one cares; just look at the number of people with only fans pages. It is a crime in most states to release revenge porn.
honestly, this sounds like a manipulative power play that will ultimately screw your ex over far worse than you if they are released.
Jesus mate I haven't been laid in three fuckin years either but it's not like she cut from the same cloth as women who do enjoy drama, you can tell it's someone genuinely in distress one as you don't end up here willy nilly looking for attention on Google that shits all on reddit etc.
You're very right though it will hurt her exs reputation infinetly worse. That's where I tried to make the point she can focus on his bravado jack the lad friends comments or talk to her girlfriends who will ingeniously be inventing new torture methods by the minute.
The 'allowing recording is a tough one' let's be real people are naive we all are by nature and make mistakes this woman obviously believed he believed in the intimate moment as much as she.
Anyway someone above mentioned if you do feel the impulse then cover your face, if they're asking for proof it's you then hold something only they know you own.
Man I'm turning into a shoddy soap opera writer. Goodbye everyone best of luck with situation op.
