Learned a lot from this site. Thanks.
At 12 my older bro told me about sex and that jacking off was normal and a great stress reliever.
I asked him if he jacked off and he said he sure did. He said there are times when a guy just has to take care of himself. It's is no big deal. He also told me to tell him when I could ejaculate... that is if I wanted to. And I did 3 months later when I turned 13.
I jacked off for him and he jacked off for me like the great bro he is. Later on we would jack off each other when one of us was stressed. And we still do.
