Human Factors
While executing a go-around; the Captain failed to reach the TOGA detent resulting in a 'Too low; gear' warning. I directed the Captain to push up the throttles. The flaps were retracted to 3 as directed by procedure; then to 1. A climb to 2;000 ft. and turn to 220 degrees was given by ATC. Upon approaching 2;000 the aircraft began to accelerate. I told the Captain to come out of TOGA but he delayed in doing so; causing the flap over speed before I could retract flaps. ATC then issued climb instructions to 4;000 ft. In the confusion of the moment; the turn to 220 degrees was delayed and a traffic conflict arose. We were instructed to call the tower after landing.
A320 First Officer reported several speed and altitude deviations occurred during a go-around; resulting in an airborne conflict.
