...but whether or not you are attracted to men or women does not generally change, unless you are bisexual/pansexual.

Generally no, but its not unheard of, so sexual identity is not an immutable feature like race or gender both of which are definable and objectively testable. With respect to legal status why don't we consider homosexual identity as irrelevant as other forms of identity, like party affiliation or religion? So for example sodomy laws based on behavior and not identity would apply to both Republicans and Democrats. What difference does any of a person's various forms of identity have to do with the regulation of behavior?
