Nice sentiment but the last swear is superfluous and interrupts the flow.
The point is that my original light is pure, so yes it gets sullied by shit, and yes if it was fucked then perhaps it can be unfucked (although is such a thing even possible - like you didn't have consent so quick, unfuck before anyone notices).
But how is this pure light, to which we're referring, a fucking light? Unless we now switch the meaning to capture the original creative purity of the sexual act without the connotations of violence? In which case, we need a better word.
Words matter.
