Sorry I've taken a while to respond to this.
Sexuality is defined by who you choose to be with in romantic and/or sexual relationships or encounters.
I think you're missing the point. Obviously who you choose to be with is a choice. The real issue is whether a person can choose who they are attracted to. For example, there are many people who are attracted to their same sex, but who take part in heterosexual relationships because that's just easier in our society. According to your definition, would those people be straight?
