I think the terms heterosexual and homosexual can be ambiguous in the context of gender transition. Nobody's ever entirely sure what sex they're supposed to be relative to. That's one of the reasons why I identify as a lesbian, which makes matters a lot clearer. I guess we could try to popularize the terms gynophile or androphile, but that kind of sweeping change sounds like an uphill battle.

Back to the original question: no, nothing has changed regarding who I am attracted to.
