Could it be since he brought it up that he wants to be overpowered & will only put up a token resistance? The first time you go for a tender area & inflict a little pain he will surrender & be yours totally?
I saw this once where a woman made a big deal of not submitting no matter what the torture inflicted on her. So 2 of us women took her for a session & after just a few minutes of pain she surrendered completely & is a great submisive now. She only wanted to be made to accept her place & felt if she resisted a bit before she gave in then she could tell herself that she had tried to hold out but had to give in eventually. Maybe yours has the same attitude?
