Let's try this again...

What is condensate if not steam that has been condensed? If you have
condensate on the walls of your bathroom after having a shower, how did
the condensate get there? Was it a "miracle"?

Now, let's look at fog. Fog is technically water vapour which has
condensed. Been down to the river lately. Go down there on a cool
morning sometime just as the sun is rising. You will see "fog" rising
from the water. This fog is just condensate. It was given off from the
surface of the water as steam or water vapour if you prefer. You cannot
actually see steam as it is, like water, colourless. What you see is the
steam as it recondenses back to water in the form of fine water droplets.

Steam will not exit the shower head but it will be given off from the
water surface as the water exits from the shower head. This is a process
known only to JHS students (obviously) as "evaporation".

Evaporation seem to be a miraculous process

Now, since you have a fixation on steamy sex, explain to me the origins
of the term. Better yet, it might be best if I explain it to you since
you seem to think it's a "euphemisn" (sic). I suspect you might have
meant euphemism! You seem to have a poor memory of your last sexual
experience so I suspect it may have been a long long time ago or
possibly you may never have had one. At any rate, "steamy sex" can be a
quite literal term, you just need to get into the deed with a little
gusto and, no, masturbation doesn't count!

When we humans engage in physical activity (sexual activity included) we
generate excesses of heat. Since our body only operates properly at a
very narrow range of temperatures, we need to get rid of this excess as
soon as possible. How do we do this? It's simple, we sweat. Sweating is
the production of a fluid consisting primarily of water as well as
various dissolved solids (chiefly chlorides), that is excreted by the
sweat glands in the skin. In humans, sweating is primarily a means of
thermoregulation, although it has been proposed that components of male
sweat can act as pheromonal cues. (There's that sweaty sex reference
again). Anyway, evaporation of sweat from the skin surface has a cooling
effect due to the latent heat of evaporation of water. Hence, in hot
weather, or when the individual's muscles heat up due to exertion, more
sweat is produced. Sweating is increased by nervousness and nausea and
decreased by cold.

Even though my wife thinks I'm pretty "hot", it's quite obvious to me
that my sweat never reaches the boiling point of water. Therefore, it
seems that evaporation of sweat from my body (and yours if you ever get
lucky!) occurs at much lower temperatures than 100C (212F) Can I see my
sweat evaporating? Not unless it occurs in vast quantities (at 74, I'm
not quite that hot any more!) or there is a cool surface such as a
mirror for the water vapour from my sweat to condense upon. Just to
clarify, we don't have ceiling mirrors in the bedroom.

Animals with few sweat glands, such as dogs, accomplish similar
temperature regulation results by panting, which evaporates water from
the moist lining of the oral cavity and pharynx. So dogs, it would seem,
do not engage in sweaty sex unless of course you consider panting to be
sweaty sex. Poor dogs!! Come to think of it, many of my friends from my
younger days used to pant at the sight of a hot girl down at the beach
so maybe dogs can have a variant of sweaty sex.

Anyway, you stick with your "poetry" and your "poetic license" and I'll
stick with the steamy sex. I sincerely hope you get lucky someday and
understand that steamy sex is a literal term. Lack of experience is a
real bitch!
