Yes it does sound weird. It does sound like he is being sexual with you. My guess is he would not admit it openly. He has nothing to gain from admitting it. It also sounds to me, like other posters have said, that he is being controlling with you and your money. I agree with what Sandman said though. Did you give him permission to take your paychecks? Can you take control of your own paychecks? I know that's not what concerns you most though in your OP. It does sound like your brother is being creepy (sexually) and inappropriate with you (sexually). Is it hard for you to be assertive? Can you stop wrestling with him? If he were to initiate wrestling around, would you be able to say no? It does not sound like a healthy or safe situation to be living with him, in my humble opinion.
