He can't control what he dreams. He was dreaming about the dad, and getting a boner due to the dream about the dad, who was sleeping *naked* right next to him so it's no wonder he ended up having a wet dream. That's not bad, what is "bad" is being awake and not doing anything to cover it and hide it from the kid (or not telling a "white lie" if the kid still sees it by accident). It was unnecessary to feel ashamed and moreover if he let that shame make him take forever to get going with what needed to be done in that case, which is to quickly go hide in the bathroom and get it "solved", either with a cold shower or something, when the boss told him to "take care of it".
He got hard cuz of the dad and the dad saw him of course he'd react like that I mean if the author is trying to create a character that's human their emotions would get the better of him and when someone is embarrassed its hard to act Rationally. but that ends our discussion I could care less but yeah you have good points to so whatever just wanted to put out there that he could get hard because of his body or the dream even if there's a child or a pet next to him (づ ̄ ³ ̄)づ
Lol I completely understand why he felt that way but him not moving could've only made matters worse for himself if the kid would wake up and saw it (though like I said, even then he could still have told him some white lie if the child noticed) but staying there all ashamed would only served to make even the kid start suspecting something was wrong and worrying over nothing, which is why the dad finally got impatient and tossed the mc into the bathroom, lmao.
Haha, yeah, and it's fine. It's just, believe me, the kid would have noticed him being ashamed and might have started worrying, maybe even somehow gotten the wrong idea that "having hard ons is bad", or something to feel ashamed of... so that's why I think one must always think of the baby first, embarrassment be darned. Parents deal with stuff like this in this way, all the time.
it’s weirding me out that he got a boner next to a child
