For lay practitioners there is the precept of sexual misconduct which goes through not harming, not abusing and not cheating if you are engaged in a love commitment. So sexual or gender orientation seems to be irrelevant any time this precept is observed in its wholeness.

There are also the eight and ten precepts that can be observed by laity and have to be observed by Bhikkhus and Bhikkhunis. With them goes sexual abstention and abstention from wearing garlands, perfumes and cosmetics.

So, IMO, the chosen gender and sexual orientations are OK until the sexual misconduct precept is observed. If one chooses to observe the eight or ten precepts the gender and sexual diversity becomes irrelevant.

I think that the issue becomes a fetter for awakening if one gets enmeshed with such issues, as any other aspect about craving, clinging or self identification.
