Re: erections during the night
It's highly unlikely you'd ever roll over and hurt it. So unlikely that you shouldn't worry about it. the main time people break their dicks is sex with somebody on top getting off it and missing the hole like that. and sitting down on it. very painful, so painful that if you started to do it asleep your body would stop you and you'd roll the other way.
And yes, jcking off 1,2,3,4,5 or 10 times a day is normal as long as you're not missing out on life or rubbing blisters. I average 1.5 a day or so.
