I don't know. I can't think of a situation I would say that. But it doesn't come as a strange sentence to me. I just imagine a girl saying that.
I would rather say: Eu não estou afim de sair, Não estou querendo sair, Não estou bem para sair, Não vai dar para sair, Não estou com vontade de sair.
But it all depends on the situation as well.
