I wouldn't see that as a problem. Maybe your issue with it is causing him to hide it even more, thinking of leaving him over it, he probably knows how deeply you feel about this? That is a pretty strong reaction. I don't feel the need to disclose every girlie secret of my private time to any man. Why the need to know everything he does in private by himself? Could you imagine a man obsessing about your vibrator(if you have one) and what kind of a man would husband would he be if he thought of leaving you for using it? What about your personal intimate time alone? I gotta give credit to men here, no matter how much porn I watch they never give up on me. That was a joke btw. Be glad it's not two real women he's watching and be glad you have a husband of many years, and beautiful children. Lucky you!
