My Brother, My Love

What is love? And what is sexual feelings? And for anything sake just tell me why should one do not consider to see a doctor and instead decide to have sex with his or her siblings! Why is it so important to have orgasm with anything you think is right!? Why we don't accept some limitations?! Have sex with anything in the world except your family! Is that hard?! If it is! Then just consider to see a doctor and make sure you're doing not a horrible thing! As a person who don't believe in god or Jesus or anything in the other fairytale land I have to admit that I can keep myself together and don't think about having sex with anything that I have feelings about , I am sure that it won't kill me and I won't kill myself and life goes on!
