It is not immoral to take videos of your sexcapades if you want to. As long as your intent was to keep those between the two of you, the non-violating participant did nothing wrong.
If you don’t know that, you picked the wrong profession.
Agreeing to be filmed while having sex is a moral violation on both sides.
To continue this discussion would be pointless; I’ve said my piece, you said yours, we will let people decide which moral code they wish to follow.
Have a good day.
