[55b bottom]: Gemarah: What specific act is defined as the beginning of intimate relations (which one would have completed a marriage or violated a prohibition for)?
RambaM: Everything in this world created by Hashem is by definition Holy and pure. Even the language of Hebrew if called Lashon Hakodesh (the holy language), and has an appropriate time and way to be discussed [even the intimate act of relations is only written as “Bi’ah” (to come together)].
Sforno: When Adam and Chavah were originally naked they were not embarrassed. They had no reason to be ashamed because every part of their bodies were functioning equally to serve G-d [eating was the same as having relations].
D-E-ep Thoughts: Our bodies and mouths must always remain pure and holy. We are given such wonderful gifts to be able to elevate our souls and we must never debase them. When a body drives the soul (G-d forbid) it is like using a tool for the wrong purpose; not only does the result not get accomplished, but the tool gets damaged in the process (like trying to use a cell phone to hammer in a nail). By speaking clean and nice words (never using our tongues for slander or swearing) and by keeping intimacy focused properly (only between spouses and at the proper times) our souls are able to use our bodies as vehicles to actualize amazing spiritual potential.
