...Look at it the other way - if you asked a provider you've only seen a few times if you could record the session, do you really think she'd let you?  No way!

Trust is a must.  In this hypothetical, you don't know her that well and you don't know what she'll do with it.  If she knows you're married, she can use it for future blackmail material.

If she filmed you with your knowledge or without your knowledge but she does not have a legal signed release ("2257 release form") then I think you can get her shut down and probably arrested pretty quickly. Granted, your movies will still be all over the internet (once out there, it stays out there).

Even if you LOOK old and waaaaaaay over 18 yo, I think she still needs a signed 2257.

That would be the most expensive free fuck you'll ever see.

So if it's someone I know, damn right I'll be the male talent. Especially if I'm not paying for it.

... unless there is an ugly man fucks escort porn niche out there.

just boredom or something else you're doing?

Have mask, free session.  

What's not to love.

Of course I would...

let them ask "who was that masked man?"

I am not doing porn for a free lay. €10,000 or so and a free lay, maybe. But just for a lay no thanks.

and aging body type, I would break the camera.
