Is it wrong to give an identical twin brother a handjob?

I would say it's a matter for the two of you to discuss. I know twins, especially identical twins, tend to share a special bond that those of us without can never hope to fully understand. From an ethical POV, as long as it's a mutual understanding thing, not one taking advantage of the other, I see no issue with it.

 

All I'll say is you'll very likely regret it when you're adults because it's a social taboo in our culture. Do you want to be lovers with your twin brother too, or just twin brothers?
Do you have to experience EVERYTHING together?

"The foolishness of youth."

My opinion. You asked.

 

Wrong on so many levels don't do it, you need to go out and find someone else to experiment with. Where do you stop with experimenting

 

I thinks its OK as long as both of you are 100% with it.. Its really common for brother's and really close friends, it happens more then you think its just not talked about but it all goes to how comfortable you both are now anything more then a handjob maybe oral but more is or might be weird my opinion

 

Ethically speaking, as long as it's consensual, I can't find anything wrong with it. Most people that say otherwise have no reasons other than "it's gross/disgusting/wrong/your sibling" and never explain why it is so. (although I'd probably check the laws where you live)

 

Be aware that this is textbook incest. That's all I have to say.

 

I'm gonna say one simple thing: You can do whatever you want, but my answer to your question is a big fat "YES."
