My theory is that she would feel threatened if she knew how often I do this. I'm as discreet with it as I can be. For the past few years I've taken to quietly doing it in bed virtually every night - I just quietly jerk off into the sheets. My feeling is that if I took a magazine into the washroom, she would feel "pressured" by this. I'm not sure if she's aware of my movements at night... I do know that sometimes she's awake while I'm doing it. At the moment it's not something we acknowledge or talk about...
BTW, I just had an eye-doctor appointment, and I do need a slightly stronger prescription...
