The situation has been covered before, but this appears to have a new twist.
"I live in a house as a Brother-Husband. There's four of us now and it's all fine. Everyone contributes to the finances and stuff. We all sleep in a sultan size bed and there's sex damn near every night. Who could complain about that? The problem arose when I couldn't sleep. I didn't want to disturb everyone and I went out to the livingroom. I had a nice long and slow session of masturbation. One of the guys found me asleep on the couch in the morning covered in dried jizz. The pouting started and hasn't let up. I don't get what the problem is. Everyone reads your blog. Maybe they'd listen to you."
Well, alrighty, then. Yes, we've covered this issue before when guys have written in about wives/girlfriends getting jealous over the jacking off. I do have to admit I'm surprised that guys would be upset over this. But, we're all human and our feelings get hurt.
Listen guys: Masturbation is a wonderful sleep aid. Sometimes we just want to get our rocks off without worrying about satisfying anyone else. Both those situations are quite normal. Now you're making him feel guilty and shaming him for that.
Sure, he could've remained in bed and gone at it, and risked waking the rest of you. Instead, he went elsewhere to achieve what you all had: Sleep. He thought he was being considerate. I think you need to cut your Brother-Husband a break here.
