Yes, I share a bedroom with my youngest brother, and he's walked in on me jacking off, but then, I've jacked off with all 3 of my brothers, so it was no big deal.

Same with me. My brothers don't actually "catch me" as much as just walk in on me.

In a sense we should always talk of being walked in on, rather than being caught. If you were using the bathroom and someone walked in you wouldn't talk about being caught pissing. Jerking off is as normal as that, and no more wrong than that, though obviously a lot more fun.

That was really well thought out. You're right. If somebody sees me, they walked in on me. Yep. Beating off is a whole lot more fun.

Yes, my brothers have seen me do it and I have seen them. There really isn't a reaction just like have fun and I'll come back later.

Back to actually answering the question, I have not been walked in on as such, though my brother has seen me wank*.

When I was in secondary school I would usually take advantage of the fact my brother and I got home from school about half an hour before my mum got in from work. Usually, he would be watching TV so I would go to my room and have fun relieving the horniness I had built up during the day at school.

While he was pre-pubescent I was careful not be to walked in on, but this got a little frustrating as he would sometimes come to my room to ask me something or to borrow something and I had to keep an ear open for him approaching and be prepared to stop, put it away, and pretend I was doing something else.

Once he was starting pubery himself and I thought he would understand, I explained what I usually did immediately after school, thinking this would be the end of interruptions. I don't think I had really thought through what his reaction would be because he then asked if he could watch. Having described wanking as this really normal, fun thing to do I couldn't then get shy about so I let him. For the next few days he watched me each day after school then the novelty wore off and he went back to usually watching the TV. But that did mean that now it was out in the open I didn't have to stop if I heard him approaching. He knew what I would be doing so if he walked into the room anyway that was his choice so if he came to ask him something I'd usually answer without stopping, though occasionally, if it was something complicated, I'd have to tell him I would think about it properly once I'd cum.

Anyway, this thread got me thinking about a poll, so there is a follow-on at: Sharing a Room and Masturbating

* wanking is UK slag for masturbating,

My brother walked in on me when he was 11 and I explained what I was doing. After that I was careful not to let him see me until he began to masturbate. Now we do it openly

Yeah this has happened a bunch, eventually it gets less awkward and just starts being annoying. Kind of to be expected though I guess, small house + 3 teenage boys = a few awkward moments

as far as brothers go there is no catch just walk in and see each other. We just leave each other in privacy. As long as parents don't see.

never. i lock the door.

Happend a few times.
we respect the privacies

it's hard not to walk in on each other at least once in awhile when you share a room. My brother's were a little shocked the first time but at this point its second nature and no one cares.
