This is why I really like the Fate social combat system, you can /always/ concede if you are losing, it's incredibly hard to be one shot, and if you concede you get to choose how you get taken out of the scene. So if you don't want to be seduced, have your character get frustrated at the constant seduction techniques and they leave/go home.
You would only get 'seduced' if you resisted the seducing to the point you had severe psychological issues (big complications) and they had the opportunity to dictate how you were taken out.
I don't know why people are so against the system when it handles social combat so well without removing agency unless you simply refuse to let someone 'win'.
