Do men think videos of a potential date blowing another guy is sexy?

So my friend is recently single and has started online dating. She's 30, pretty, and has a great personality and sense of humor. She's befriended this guy online who she's met a few times in person. They haven't slept together. He is pretty blunt and open about the women he dates and it sounds like he's mostly looking for sex. Today he told her he cancelled a date with a woman. She was sending him nudes, which he loved, but then she started sending him videos of her giving blow jobs to other men. Now my friend is convinced that ALL women are doing things like that and it's something every single guy out there will want. Personally, I think it's disgusting and skanky! Any guy I've dated would've immediately stopped talking to me if I'd sent him a video of me blowing some other man! Am I missing something? Is this a thing now?! If THAT'S the kind of men out there, I'd say she's better off single!
