I guess what I am trying to spot is: When you speak of conclusions, what do you start from, what are the premises, what are the points you accept as relevant on the way from the starting point and the premises to the conclusion?
These are fair questions.
Let me ask you this rhetorical question: how did you form the concept "mature" -- as in "mature behavior"? (Just an example.)
My guess is that this wasn't the result of a strictly deductive process, but came from integrating different ideas, observations, experiences, etc. It may be difficult to explain the full process by which you formed such a concept.
Regarding sexuality, I'll offer some of my views.
The mind-body dichotomy is false. As living persons, we have both mind and body, and both form a single, unified whole. As such, sexuality is no less a mental phenomenon than a physical one.
Also, it is dangerous to treat reality as anything other than what it is. Reality is what it is, not what we might like it to be. To treat something as something other than what it fully is -- even unintentionally -- carries risks and the potential for mistakes.
And so, is dangerous to treat oneself or others as disembodied minds (or to treat the body as a less important "part"), or as unminded bodies (or the mind as a less important "part"), and that includes sexual treatment.
Falling on the "disembodied mind" end of the spectrum, the body will be seen as a prison that may be shameful or threatening to one's "soul". The body will be at best the source of one's "lower nature", and viewed with suspicion.
On the "unminded body" end, the mind may be seen as a threat to one's bodily interests. To deny one's bodily urges will be seen as denying one's fundamental nature. Sexual encounters will be little more than scratching an itch and will have no particular meaning, because the mind is the realm of meaning. Sex becomes mutual masturbation, and you might as well be having sex with a fembot.
My biggest issue with treating sex casually is that it seems to treat people as mere bodies, and not as complete persons. Also, it seems to treat
oneself in that same way. (I should reiterate that I don't view
all "one night stands" in this way. It is rather one's overall
attitude towards sex; its role in one's life-plan. Sexual experiences can be stepping stones to something else.)
My views on sex arise from the requirements of integral living. In this view, an integrated view of mind and body, I think it is natural to gravitate towards a view of sex that respects both, and I think this leads to a "romantic" (or meaningful, or personable) view of sexuality. When one is attentive to the existence of one's partner as a complete
person, then the kind of intimacy involved in sex is going to
mean something, and that is likely to preclude taking it casually. It will likely involve hopes for something more, if it isn't fully valued for its own sake.
The reason why I made a concession to sidhe regarding "religious sex", is that it just might be a form of sexuality that preserves meaning, and therefore might be an end-in-itself (or "sacred").
Anyway, I'm out of time for writing this post.
