Can this damage my led?

AWOL:
So now are you buffering this?

I'm pretty new to Arduino and electrics and don't really know what you mean. Though I'm going to say no.
I described my exact setup in the first post, there's nothing I left out to make the description shorter. So, 5v -> +first led -> -first led to +second -> -second to 33ohm 5V resistor -> Digital3
