There a number of things I might ask you to allow me to point out.
In a truly advanced civilization (and really this means mentally advanced under aknowledgement of the Unity of the spiritual reality, more so then physically and/or technologically) - the upbringing and caring for small children would NEVER be imposed onto very young biological parents, themselves attempting to 'find their place' in their society.
Sexual selfexploration and being a full such ET being would not be suppressed by taboos and laws of do nots, as such a civilization would long have recognised how to attune with the natural biological rhythms of life.
So when natural biology 'kicks in', say in ET puberty, all available data about what is occuring would be freely shared and conveyed to all such young ones experiencing say biochemical changes.
Consequences and outcomes of engaging this newfound form of ET selfexpression would be common knowledge and as NO sexual taboos would exist as dogma, abberative and/or selfdestructive and abusive behaviour, caused by emotional and mental disharmonies would very rarely surface in such a society.
Having such a basis; should very young parents -produce children, then those children would become harmoniously integrated in a Greater Family, consisting of caring elders specialising in looking after and tutoring all children.
Parental responsibility so would not cease, but be greatly diminished in a shared community, honouring and treasuring the young ones as being the backbone of their growing ET civilization.
There sio would be 'specialists' selfchosen, who would allow a general and ubiquitous harmony to prevail in such a mentally advanced ET civilisation.
It is easy now, to project those principles of harmony and cohesion onto other avenues of this society and witness a rather different kaleidoscope or structure underpinning this civilisation.
In simple words, older children having children, because mother nature drives their hormones to reproduce, is, following thorough education, no big deal. All children know their parents, and their elders and their carers and their tutors - all are family.
Secondly, a truly advanced ET civilization would Understand the natural rhythms of the body and know when the biorhtyhms are most likely to produce ovulation and possible insemination.
A female ET would know her body as her temple and ambassadoraship of the universe 'Mother Nature' herself.
Like Terran fauna 'gets on heat'; an ET female would know her 'heat' and if pregnancy is desired, then the 'heat' will enhance probabilistic outcomes of success.
As you can see the Terran civilisation is NOT a mentally advanced civilisation; but rather a civilisation which does not understand its Mentality at all.
Human Mindedness revolves around its emotional responsesiveness to environmental stimulus.
Reaction and Inaction, Fight or Flight and pondering and fence sitting and recycling the old dogmas, ideas and archetypes over and over.
No bigmo; Jesus and the apostles did not have sex orgies with Magdalene and her disciples.
However Jesus initiated all of them, brotherhood and sisterhood in the secrets of the Kundalini.
Mary Magdalene was the Lover of both Jesus and John and Jesus did share intimacies with both of them.
Not the pornographic nonsense of the lower levels of the emotional physicality, but the secrets of the tantra and the eroticisms of the classical Egyptians, Greeks and Romans.
These secrets are about harmonizing the emotions with the physicality through focused thought and invoking the Holy Spirit to participate.
The the human sexuality becomes like poetry and music singing melodies to the spirit in a fusion of the human merkabah or bodytemple with the merkabah or shape of the universe in say a morphogenetic resonance; a holofractalisation or a simple blending of polarities as a Russion Nested Doll 'Babushka'.
The invokation of the 'Holy Spirit' then interacts with the encoiled Kundalini as the base chakra say and this interaction IGNITES the serpent, say as the arousal of the male phallus.
Unlike in lowerD sexuality, the unified form is not restricted to emotional-physical interaction but also engages the human mind and through and by the mind the spirit and the LOVE energy of God become accessible.
So yes bigmo, I agree with you: human sexual intercourse is hardly ever LOVE MAKING. Rather it is animal passion for reproductory purposes as designed for the fauna 'on heat'.
The Art of LoveMaking is not commonly known in the human vocabulary.
When humans are truly in love, then the mentality between them develops and harmony is certainly attainable.
But it would be so much easier to UNDERSTAND what Love Making is, before engaging the lower chakras of the Kundalini power.
So blessed are the humans who can Love one another in a continuing enjoyment of each other's company.
How many such couples do you know as a percentage of the human groupself.?
Couples marry each other on the basic levels of physical biochemistry and attraction and become either emotional or possessively attached.
Then the disharmony of cutting off the mentality to allow the divine Love to participate; they begin to abuse and hate each other in their emotional contracts.
Things become monotenous and the search for Love's fulfilment, namely the 4-dimensional unified form of the LoveMaking continues.
How long will the Divine Love continue to remain exiled by the inability of the human mentality to understand itself?
Well, the answer is one of the reasons why WE are here in Noah's Ark to redeem OUR Beloved Creator from his selfimposed exile.
Love to the Brotherhood and the Sisterhood brother Michael.
But again these initiations were mental, rather than physical, the understanding of the archetypes in a simple language of metaphor and like the mirrors I am using so often.
