I'd just add a Drush explanation in the דרך העבודה approach:

Explanation 1:

Wasting means there is no reception כלי. A woman is a כלי as the Gemmorah says עשאה כלי. In any way of copulation (vag' and non-vag') the woman is considered a כלי and therefore allowed (see Gemmorah in "חתיכה שהביא מהשוק").

When there's no כלי - the זרע goes to חיצונים and therefore prohibited.

Explanation 2:

יחוד has two purposes - 1: procreatioprocreation (פרו ורבו) and 2: יחוד by itself (the FUN). There are different כוונות of יחוד for Shabbos and weekdays.

That's the Gemmorah in Kesubos 59b: "אין אשה אלא לבנים" - procreation, "אין אשה אלא ליופי" - יחוד itself.

THe Poskim focused only on procreation, saying that even while pregnant the fetus benefits etc. But the truth is those relations are not only permitted but obligatory as procreational while focusing on the יחוד of the couple itself.
