Death or Sex?

A short poem, hopefully w/ dramatic graphic images. It can be one or the other, you choose

There's a window,
it's shining, burning rays,
white and gold rays pierce your skin.

Your hand tightens,
fingers curl, then slide down.
The light is all around me; it spills below.

I'm almost gone - you're fading fast.
Trying to think was never
an easy idea.
