Or, really, any one of my BSOs who might need to go undercover to do that particular deed against an antagonist. If I understand the phrase correctly, I think that sort of thing would count?

I think that would totally count, as much as being sexually extorted themselves. Having to do the deed creates psychological harm, and also potentially harm to their existing (or potential) relationship with Other BSO.

And yes, on self-harm in the line of duty! I would think even accidental self-harm would qualify if need be.
