Is this normal, my older brother had lusts for me & is jealous of me

He admit he «wish he could be me» when we took MDMA together, that shocked me. I knew he was crazy for me but still, that is a new low haha. i dont know if au should laugh or if i should cry lol. He steal my stuff & i have to enter his room to go and find it, next to the most disgusting items that he use; cucumbers - wrapped up in condoms - with shit stains on it….
Fleshlights, sex toys, that look dirty… He is beyond desperate & lonely - he’s not «a man» to me & never will be.
