He wants to have nikkah before meeting is that normal?

To muslim men: a man wants to have nikkah otherwise he says he cannot get physical with me. We know each other only online., daily video chats for last 5 months. He says then he will have absolute ownership over my body and for this he provides protection (he is a doctor, I am a nurse) Is that normal? We met on Warhammer forum group for the context. I am 29, he is 36 and we are both in the UK.
