>>BIOLOGICAL FUNCTION limits the discussion. ...

Hormonal cascades
from sex and orgasm are
pure biology.

They affect all cells,
every time someone's aroused.
Fertilization

just happens some times.
If we're gonna assume things,
we should assume that

ancient proto-cells
evolved proto-intercourse
as a method to

regulate hormones.
And when this biology
became commonplace --

proto-intercourse
as a hormonal control --
cell matter exchange

piggy-backed onto
intercourse. And that linked sex
with reproduction.

[King Prout]

those are derivative, supplemental, supportive EFFECTS of sex, not the FUNCTION of sex.

let's apply your "logic" to something else as equally obvious: you would say that because an eye which has a shard of glass driven into the cornea (ie: abuse or misuse) reports agony to the brain, sets off a cascade of hormones and neurotransmitters, affects demeanor and personality, and so forth and so on... that the biological function of an eye is not to focus light onto the retina, translate photon reception into chemical signals, and report this data to the occipital lobes.
