Is it normal that i showed my younger brother how to masturbate?

He's lucky that he got a brother like you.

Don't see anything wrong with that.

I think it's normal. When I was a kid I asked my older cousin once if I could see his junk. He had just got off of the shower and was sitting on the edge of his bed with his legs open enough room to see his saggy balls and flaccid uncut unit. He caught me staring and I thought he was gonna freak, but he was actually very cool and told me he didn't care if I looked and asked if I had any questions. I was pretty enthralled by all of it. I had never seen a grown up guy naked before. I never touched it and he never got hard.

I had a similar experience with my brother too. He asked me if he could see my dick and I told him no. I felt like I both made the right choice and a asshole too. Afterwards and he avoided me for a good while. I told a couple friends and they said that I made the best decision. However, I asked my gay friend and said that I should let him and that if he's gay, better me than a stranger. Eventually I asked my brother why he had asked to see my dick and apologized for telling him no. I asked if everything was cool with him and if he had questions about anything...and holycrap! Lol! He said he was curious if his dick, about why he's getting 'moist' aka precum, nocturnal emissions, foreskin, would he get bigger, his balls, jacking off, everything! Wow! We talked for like two hours. It was a good and much needed conversation. In the end the dude did ask to see my unit again. I hesitated, but I gave in and agreed. I didn't get naked but I pulled out my junk through my fly and let him have an eyeful. Without asking he reached out and grabbed it, I almost pulled away, but stopped myself. He asked if it was okay to touch it and I told him it was fine. He just rubbed my balls, played and pulled at my pubes and pulled my foreskin back and fourth. He commented how thick my dick was and if he would get as large as me. I told him as he got older he probably would. He continued to explore and as you can imagine, after a while of stimulating my junk I started to get an erection. That's when I stopped and put it away. He never asked me to see it again. By the way, I'm pretty sure he's gay.

Boys are curious about their body and will often ask brothers and friends about their penis and how it works. I jerked off with my cousin and a few of my friends, and it was fine. Perfectly normal for boys to want to know how other boys' stuff looks and works.

100% OK. People are two hung up about the naked body. Everyone has either a penis or vagina. No big deal. I much rather my younger brother learn from me, what a penis is, how it looks hard, how to jack off (I had NO clue at all--until I was 18 years old!) how to have sex with either a guy or girl (his choice).

Your Dad was ok about it so if it really happened, then don't worry about it ok.

It all depends on whether this is a true story (and with pedophiles you never know if these kind of plots are actually some perverse dream), then you should have redirected him to your parents and if they felt he was ready then you could have done a little demonstration. That said it isn't the end of the world and there are many "relaxed" families where this isn't a big issue.

Why did you have an erection while talking to your brother?

I've seen four posts related to nudism among males. They were about a naked photo shoot, a father seeing his sons naked, and a father showing the 'anatomy' of his penis to his son. Your post is the fourth. This has to stop!

That's not normal. By the way, fuck you.

because of his young age and your age difference in general what you did was sexual abuse.

The (only slightly) better option would have been allowing him to watch a pre-chosen pornographic vid of a guy masturbating or (better) some sort of diagram intended for educational purposes.

No.

When I was about 12 my older brother about 16 showed me how to maturbate,masterubation did help me through difficult times with anxiety depression and fear. My brother got out of the shower one day and I got a glimpse of his cock and he just acted normal,I was concerned about the size of my cock and how to properly jerk off and get up a lot of cum.It sounds funny but I was little scared to try it as it was a grown up thing to do and everytime I was about to cuk I'd stop because I was scared of what cumming would feel like. So when my brother got out of the shower and showed me his cock I asked him lots of questions I had in mind,he really helped me out. To help me out he ask me to drop my trousers and show him my cock,so I did in which he started touching,he got me really hard by showing me some porn and then started jerking me off,it's strange but it was an unbelievable experience. I came all over his hand as it was the first time I had cum so much came out

This is obviously a touchy and delicate subject, but I believe you handled it well. Number one, and most important: he asked, and you did not force anything on him. I know some might say "point him to a video", or maybe a book or diagram - that's tricky, because it doesn't explain things, and could lead to misuse of pornography. You let him ask questions, and you responded, so that was great! You were only sharing with him what HE needed/wanted to know. Sometimes, explaining something verbally, or watching a video, just doesn't provide what the person needs. He had specific questions, and you responded, in a loving and caring way. I would hope that you also shared with him: there's nothing wrong with masturbating; you should only do this in private (not casually around the house, or when the folks are throwing a dinner party, or at sleep overs!); if you do it with someone else, you both have to agree you want to (like he wanted you to show him) - in other words, NEVER do anything you don't want to do, and NEVER let anyone make you do things; and, that he should be free to explore and discover on his own what he enjoys about himself and his own body, because everyone is different, and that's OK! And, I hope you told him if he ever has question, to feel free to ask. Again, some might disagree - but, I think what you did was respectful and within appropriate bounds.

You did the right thing. What a cool brother you are. The age difference is maybe a concern. Guys your age, 17, have a body like a full grown man. At 9, he's still a little kid. I'm sure he was amazed watching you.
Good you told your dad. If he's cool with it then it's fine. Has your brother watched you jack off since? He's obviously curious, and your dad knows and encourages it (your dad is super cool), you should probably show him again.

I guess if there was no contact is fine and normal

I don't think there's anything wrong in it. I'm just curious why your asking AFTER the event though? Surely if this was True(?) You would have asked First? I know I would have done anyway.
