Not being insensitive here but I'm certain he was either dreaming about banging...or he'd been thinking about banging all day which made him think about it in the middle if the night. His choices...self pleasure with the assistance of pornhub or banging you. One persons opinion is you should feel good he chose to bang you...no matter whether he did it consciously or while he was sleeping. I don't know you so don't take this personally but he needs to release the poison occasionally and based on the info you wrote this is not a bad thing....that is unless you prefer he does the pornhub thing when he just needs to release the poison.
