Well, why would you worry about getting into trouble?
This is a personal question, so feel free not to answer . . . Do you not love and respect your husband? If so, wouldn't just the thought of hurting him like that make you feel sick?
This is going to sound generic, but, I think we all have different ways of expressing love.
I am the one person in my husband's life that is there beside him no matter what.
He is vey controlling and demanding, and, this is my one selfish indulgence, and, I don't feel that I am doing anything wrong, other than, being given a venue where I feel I can be myself for a few hours of the day.
So no I don't feel guilty or sick.
