I do recommend that it needs an update. It has three options using language that is not necessarily the language that the community would use.
I would suggest that some consultation would probably be warranted before deciding on specific wording, but we should look at adding additional options to that question in order for people to identify. We also need to disentangle it. Right now, the way the question is worded is primarily identity-based, but the definition that's used for clarity is behaviour-based. We're actually conflating two different dimensions of sexual orientation, which is problematic in terms of interpreting the data. We really need to tease those apart and ask separately about one's self-identified sexual identity and one's sexual behaviour.
