Sex is part of our hard wiring, in the centre of the body, the source of new life.
Sex can pit the well being of a presence, body and mind, against mere feelings, the apparent need for gratification. People love the pleasure and will abort foetuses to continue the better feeling lifestyle.
Sex involves an agreement between the persons. Involves the will.
Sex effects the most important things in life.
Friendship
Love
Esteem
Sanctity
Honour
F.L.E.S.H. and acronym.
Also it effects the history of the body as from 1 Cor 3.
And the history of the mind, will and emotions, which is profound, and a matter of honour and cause. There are soul ties. These can conflict with past friendships, present or future ones. Or our relationships with our parents and siblings.
It effects pleasure and happiness. What we are happy with shows our love, 1 Cor 13.
It effects money matters.
It leads to children, a matter of honour and great cost.
Actions speak louder than words.
FLESH... is deeply effected and even changed by sex. Changing past present and future friendship...
Lust and love compete and conflict. Love can be shown to a friend's adversary, it can be betrayal. It can end your career in politics.
What gives people self esteem? Sex effects that.
Regarding holiness, two become one flesh, instead of separate from the world unto God. It can change a person's character.
To know someone intimately, the appearance, voice, face, emotion's high's, the will, to have the focus, the choice, the seed, the inner space is a matter of honour. On a one person level, the heart and seed is the highest honour there is. A zygote were it not for other people on the world, is more weighty than the Earth.
Also from having children we carry honour. And it can be poured away into the gutter, instead of, a pond, if you like. It become a street boast. I think we can love another's honour and protect it. We can preserve it. We can be in agony if it is lost.
