I think that's fine. I'm perfectly ok with sibling and or cousin sex. Given that it is wanted and consensual between both people, that they love each other, and it would'nt result in pregnancy.
I was in a very loving sexual relationship with my brother for about 6 years. It started when we moved out on our own to a different city and shared a apartment. And it continued until he got married.
We have no regrets, and we just keep it to ourselves. We still have a deep love for each other, but we agreed to stop the sex when one of us got hooked up with someone else.
Dear Sakura I would not discern you as in incest relationship if your 'brother' is not having blood relationship with you. If you are thinking about keeping this relationship on officially then you might face legal challenges. I do agree about the unfortunate incidents between young siblings.
They try to express but we parents do not prioritize it. We are growing up and will be good parent. :) Yes you are not sick, but your acts with your sibling might make someone feel that you are (not me though).
I hope as I can understand your maturity is strong enough now to think/discuss about it and take a stable and positive decision.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
