the lovers are weeping inside

[J.M.Byrnes]

The lovers are
Weeping inside,
Lying upon satin sheets, It kind of seems off, as you read on, considering it's their first time. Plus, satin sheets is kind of a cliche image.
Ruffled and undone; Ruffled, as in decoration? That doesn't seem to fit. Rumpled maybe?
It’s a clean spring night,
The dew on the grass relaxes, ambiguous -- relaxes what or who?
The toads croak, Do toads croak?
Far off.
They glow like two bulbs, this almost reads like you are referring to the toads, and it seems a bit strong, considering the next line.
Pale in the new moon.
The lovers are young, I think you might need to introduce this earlier and more subtly.
They’re bodies are supple.
Their eyes refuse this seems open-ended, like a bit of a non sequitur, refuse what?
Stripping themselves, each other.
The sharing of flesh is
Unknown to them,
Black curling hair, both of them? And does this really add anything?
Imperfect,
Various flaws
Show themselves.
Brownish marks on the skin, I'm not really seeing that.
Layers. Ambiguous.
Awkward, worried This seems like something you could get across with action or imagery -- you pretty much do that in the next few lines.
Their aims unselfish;
He touches her forehead,
Sweating.
Her body flattens,
He hides himself.
A doorway,
Opening,
Slithering,
Exploring.
The lovers are
Weeping inside.

I get the awkwardness of the moment, the uncertainty. But I'm not seeing why they are "weeping inside." I think you at least need to hint at that. I'm also not a fan of the really short or one one-word lines -- I think you miss opportunities to control the pace in a more interesting way. It's a good theme, and you have some interesting ideas and images.
