"Having sex" is based on the ignorance of what sex means (the distinction between male and female), and selfishly believing it means intercourse, which is how they sell self destructive lust to us, by making us want sex with each other, which then corrupts us, because the need behind intercourse is the act of procreation (creation of life) and not lust (the temptation luring towards death). If we would comprehend this, by not selfishly ignoring the obvious lies offers to us, then children and procreation would find balance on a thing called "fertility", which defines individually when a child is ready to procreate without bringing harm to themselves. But this isn't about procreation (life); it's about lust (death) and so there is no argument whatsoever, just the responsibility to struggle to sustain life over death. The life of the child is attacked by one whose intent is aimed at death (lust). And just to really drive that point home...masturbation is suicide, which is why porn is free.
