Are there any providers that allow filming during a session? I definitely won't make the video public (e.g. it won't be posted on YouPorn).

Thanks

I understand that some PSE allow that (maybe extra fee?).

You might also check with Krystal of NH aka LuvKrystal - sorry I can't give you a link but you can check her reviews - she posts both here and oTher BoarD.
