Is it normal my brother got hard when i sat on his lap?

Don't talk to him about it. I usually say the opposite but in this case it's probably best to just forget it ever happened.
Men (especially young men) are not that hard to get hard. A bumpy road can do that with or without someone on the lap. Our brains have complex opinions about other people but our penises are just like: "Hey, stuff is moving - Attention!".
Don't think about the toilet stop too much - The important thing is, he was in a difficult situation and he put a stop to it.
It must have been super embarrasing for both of you and that's probably the only reason he doesen't talk to you.

I didnt have time to read all the way through this thread. But i would say that boners come out of the blue even though we are thinking of something sexually or not. Sometimes when i get too comfortable also i get a boner it dosent mean i am thinking about something sexual. For instance when i hug my sister sometimes i get a boner when i feel comfortable but it dosent mean i am thinking of anything sexual about her and obviously i dont want to do anything with her. She is my sister and would never feel like that. But the boner will still be there regardless of what happens and it will really be awkward. Sometimes what i do is masturbate after this and make the boner go away but i dont think about my sister when im masturbating. I think your brother must have done that to get rid of the boner in the toilet. Obviously u cant be angry with him. Cox i dont think he will think of you that way. Boners can be fucking difficult for guys sometimes.Boner can appear out of the blue and can be hard to get rid of but sometimes it may not appear when we need them.

Its fucking hard being a guy so cut us some slack :(((

You owe him sex, and that is the only thing that can solve this problem

If he has said he is upset than yes talk to him ask him what he wants from it,tell him you are flattered he got hard over me and he felt like he is a good size,tell him how you wanted to grab his shafts and stroke it but there where people around, obviously he is upset you haven't ask him to do anything yet,coz he got hard for you and it feels like a slap in the face being rejected at least lay there naked for him and let him masterbate on you see if that turns you on enough

Okay, what I think you should do, is try to start a conversation, if he avoids you, ask him why. Look for facial indicators, if it's obvious he lying, then you know why. If he engages in the conversation, try other things, like playing games together, repeat until he avoids you, and go back to asking him why.

talk to him ask him about the hard ons and you guys might want to try it with all pants off

I created an account too just to tell a little about my story, wich is a little different than yours. But maybe it might clarify something (or just confuse more). My sister and I use to play a lot we were fighting, in many times she sat on my lap and had an erection. She never said anything but I can tell she felt, 'cause, how can I say without been rude? - my thing gets very evident. We never spoke about this and it always occurred. It means I started to be sexually atracted to her. I started to be always hard when we touched each other. When I was a kid, I innocently used to play with her feet too. Then I started to be very excited touching and massaging then. She used to put both feet in my face a lot, for hours. I guess what I am trying to say is that men think kinda differently, and you guys, specially your brother, may start to think about you sexually. That might be the cause of his anger and distance. Forgive my english, it's not my first language. Or the 2d lol. Now you tell me. Is it too weird/wrong what happened to us?
PS: We never said a word about it.

It is perfectly normal for him to get an erection. Cocks work that way. And no, never mention it him. Keep it your secret and if you liked it too, enjoy the memory. But no: brothers and sisters should not have sex together.

His reaction is quite normal. Apparently you enjoyed having caused him to have an erection, and I detect a desire to have sex with him. Pity he is stand-offish.... Invite him for a shower next time the two of you are alone at home.

Try apolagising for that night even if you dont mean it and use that to start the conversation. You need to speak to him about this or else it wont go away. Also i posted a more sincere post but it didnt send so theres this instead :/ also i just created this account to try and help you out :)

You need to speak to him one way or another. Try starting a conversation by saying your sorry for that night even if you don't mean it as this may help him be a little more neutral towards you then persist with the conversation. And you need to speak or else its going to stay akward and he'll probally still bemad (for whatever reason). And if after a whole year hes still like this you could always ask your parents to speak to him- good luck :) and i literally just made this account to send a reply to try and help you. :) also just ignore anyone big a butthole on here. Im guessing that it wasnt sexual etc too btw.

Are you his brother? If so, I think it is safe to say that he is gay and may want to have anal sex with you in the near future.

That's a good first lesson about penises. Most girls think they are interesting. But never to worry, someday you will find the perfect penis attached to some guy for your exclusive use.

You know what's not normal is you being a fucking cock teaser. A decent well respected loving sister would have went out of her way to give her brother a little release. Instead you let the poor bastard go into a filthy, smelly public bathroom to ease the pressure from his blue balls. I hope your fucking proud of yourself cockteaser. Make it up to him you dumb cunt and then post back and let us all know how it was!

its normal. if you liked it you should tell him and try some things with him
