Having raced into a 29-0 interval lead last weekend, Flutey's second try shortly after the re-start took England to 34-0. But the only scores after that were two French tries as the game ended 34-10.
"We take a lot of confidence out of the performance. But now we have to look at the second half and see how we can put together an 80-minute performance," said Flutey.
"It was obvious guys were beginning to understand their roles and responsibilities in attack. The set-piece moves went really well.
"It was nice scoring in the first few minutes and having the crowd right behind us from the word go. That was fantastic - just awesome."
