Can a person be a man AND a woman?

That depends on what you mean by a "man AND a woman". There are people who are hermaphroditic, meaning they have sex organs for both genders, so they could technically qualify. There are also people out there known as "transgendered" and they could count as well. A transgendered person can have a male body with a female mind, or a female body with a male mind. Their sex (meaning sex organs) and their gender (meaning what they identify as) are opposites, so that could technically count.
