i am 40+ year old male- Married- kids- Lately the sex life has not been that good- I masturbate 3-4 times a week and have no issues but it seems I have a strong need to be "viewed" or watched while doing it. (my wife wont)- it can be a complete stranger but it heightens the arousal and erection so much more- I was chatting with a friend on line and I was so turned on by the thought of someone "catching" me in the act- Is this normal and what do I make of it?
