To answer that question I'd have to ask, at what age? As a preteen I would have said yes. At that time I wasn't whacking off and I didn't enjoy wearing a hard cup. I liked getting kicked down there even less.
But from the age of 13 up I would have said, No way! I was enjoying my penis too much to give it up even for a limited time. Also My dad would sometimes take me to a nude beach. As an 11 year old I would have probably been OK going there smooth if I wasn't the only one. But at the age of 13 I would not have done that.
How about you? Does age matter?
