I imagine it'll be halfway between a GFE and  PSE (Pornstar Experience). So something quite intimate and gentle that could then progress to something a little 'raunchier'. I'd think that he just wanted you to be very passionate and act like you can't wait to get his clothes off maybe. 

It never hurts to be crystal clear so maybe ask him if that's what he had in mind as only he knows really.

Yes, it's what I did... I replied asking him the meaning.
but have not had yet an answer since yesterday.... I hope it's not another waste of time
