This is really good, and i love it! I only think that this line:
"Start with your cool lips lightly on my collarbone." seem to not really fit werll with the rest of the poem as it seems too long? Just a thought, anyway, keep writing, its amazing.
Winter pale, the line of ribs
below your strong shoulders
rise gently with each inhalation.
The snow has begun to stick now
after last night grew slick with ice
and transformers exploding along the street,
the occasional flicker of house lights.
