I mean, if that's the way it is, then that's the way it is. Maybe it's as simple as living within the constructs we're officially aware of. And if that assumption is made and decided on, then all of this hubbub over same-sex relationships is justified.
Maybe whether or not God could have done it another way, this life has a prescribed purpose, and procreation is central and essential to this life's purpose, and he set us up to need penes and vaginae to procreate, end of story. Naturally, God is a 'he', and a heavenly mother exists necessarily because God needs a heavenly female to complement his heavenly maleness in order to heavenly procreate spirit children. But we don't talk about God's wife...or wives...because she's...they're...so sacred, implying, of course, that God The Male Father is not as sacred because we talk about him all the time, but that implication is not sacrilegious because...well, they just have different roles, so they're equal but our mortal existence only deals with him...for some reason...maybe our heavenly moms needed a break after birthing so many billions of spirit children and they're off getting heavenly spa treatment on the other side of the galaxy... Where was I? Ah, right: So procreation (by divinely arbitrarily chosen method of the union of sperm from a male and egg from a female) and raising souls unto eternal glory is our primary source of purpose and joy, and therefore any deviation from that leads to only partial, or limited, joy and is therefore regarded as 'sin'...you know, for our own happiness.
And within this template, some of us are just tested to see if we'll abide by that system by choice, and in the next life, we'll all be all fixed up into proper, binary male-or-female fashion and rid of any messy wiring which had us attracted to the wrong sex. Maybe hermaphroditic humans are actually just tweaked telestial bodies of a fallen world housing sexually dichotomous 'spirit bodies' and will, in their perfected form, be changed to perfectly sexually differentiated resurrected souls with accompanying, perfectly differentiated and dichotomous gender traits. And we'll all be properly paired, penis-possessors with vagina-possessors (in a one-to-many ratio for maximized production volume, assuming there are that many more vagina-possessors in celestial glory than penis-possessors...perhaps God created more of the former or made them more celestial-prone for this very purpose).
wrasses change sex depending on social triggers, and certain snails have mastered hermaphroditic sexual reproduction, gods still absolutely need a penis and a vagina to determine pairing and reproduction. It seems, to me, a touch...inelegant a solution.
But hey, rules is rules. If that's the way things is, then that's the way things is, and we'll be blessed for abiding by it and not rocking the boat to churn up the discontent of the masses even if I'm on to something, here. So we needn't ask questions like whether celestial animals will reproduce, and if so, whether celestial snails will therefore be made male and female in order to follow the "perfect" celestial order of things to match eternal 'gender' roles, or whether they just have their own perfect pattern not related to ours. ...And whether any of those poor, hermaphroditic snails who felt like a male trapped in a he-she snail body will--gotcha!--turn out to have been female spirit-snails all along! We mustn't wonder whether eternal sex, let alone gender, is much more nuanced and complex than some binary male-female physical/spiritual dichotomy or whether males can appropriately and divinely possess traits that happen to be more often found in females but aren't inherently 'feminine' in some eternal sense. That just gets all kinds of intellectually and emotionally messy. No, better to just play along and focus on other easier-to-digest things, like the ward chili cook-off!
What a hoot if we get to the other side, and God hugs us and says, "Hey, so...my first announcement for you newcomers: we're all hermaphrodites here, and gender is more about your traits and complementarity than your gonads. Sorry. I just didn't know how to tell you all in a way that wouldn't make your brains go mushy or throw your sense of gender identity all wonky, so we sort of enforced the whole male-female thing and had that same-sex marriage fiasco to deal with. What a mess, but hey, for your obedience, here you go: I've put a little extra joy in your heart. Doesn't that feel nice?"
