The first piece of advice I have to give is:
If you meta-consent to this, expect to have mixed feelings about your meta-consent later.
Expect to NOTICE all the ways you could get back at your boyfriend, and fuck him over socially/legally/emotionally, after he does this.
Expect parts of you to experience it as "too real", and need to inflict emotional injury on him for having done it to you, while other parts of you experience it as "not real enough", and need to inflict emotional injury on him for having not given you exactly what you wanted.
In short, realize that you're putting him into far more danger than he's putting you into.
