I've never felt "pressured" or anything of the sort. I do enjoy having 1 on 1 time with her. I've found the dynamic is different with him in the room vs just her.
In my experience women will also do and say more kinky things when their husband is not in the room. They are free to be slutty without their husband judging them. I've had wives do things and then tell me not to tell their husband because she would never do that for him.
