One thing I'd like to point out in my experience, and where one of my hypothetical situations comes from, was when I was in the navy, in boot camp. The first few weeks there wasn't anything, probably due to the heightened stress everyone was under, but as people adapted to the situation, people recruits would excuse themselves to the bathroom at night to "crank one out", just because having a wet dream in an open barracks was a far more embarrassing thing that could happen, and you couldn't shower on your own, if you had a wet dream, you were just going to stink like sperm all the next day until the evening shower.
There was no rated R movies, no sexuality, the only exposure to any women whatsoever was barefaced female recruits that were just as haggered from sleep deprivation as we were, trust me, totally unappealing. There was no porn, no sexy billboards or magazines, no sex laden tv shows, there was none of that. It's boot camp, the only time you get off to do anything aside from learning, drilling, and PT, is at lights out to sleep, and on sundays to go to church and read letters from your family and maybe write a few back.
... and wet dreams were still a common thing and feared in that setting so the young men masturbated, with no aid from porn, or any visual stimuli, just to get it out of their system in a way they could control, vs having an uncontrollable and humiliating experience, and even once you were out of boot camp, you had male roommates "doing your thing" in the bathroom when you have some time alone.. was just preferable to waking up in the middle of the night.
It's not always r rated movies, porn, or sex in entertainment, sometimes it's just your body needs to get rid of something and stop holding it in.
It's not even enjoyable in that setting. It's just like having to go to the bathroom to defecate, maybe a relief when it's over but something you didn't really care to do.
If you've been married for a long time you probably forgot about having to deal with such things. Especially if you got married at a young age.
But I can virtually guarantee you, there's not a single young man alive, Christian or not, that doesn't either touch, fornicate, or deal with wet dreams at least a couple times a month.

Just like defecating, it's something your body will do whether you want it to or not, and your only real choice is do you do it in a toilet where it can be gotten rid of cleanly, or do you crap your bed.
