The former Wales international is in the final year of his contract at Rodney Parade and will turn 37 in February, but he insists he still has the drive to succeed and is determined to continue playing beyond the end of the current campaign, preferably with Dragons.
"I would love to go one more year professionally," said Henson. "I'm hoping to get another contract but there's a lot to do yet. That's a big drive for me to get that next year."
Henson spent the second half of last season on the treatment table due to a hamstring injury and he acknowledges he faces a battle just to secure his place back in the team, but he is determined to seize any chance he gets under Dragons coach Bernard Jackman.
"It's a little bit different now because I'm getting older and they have recruited well," Henson added. "I have got to take a little bit of a back-seat to start, to see if those boys take their chance."
Henson is into his second year with Dragons having joined from Bristol in 2017 and he has enjoyed a varied career, representing the likes of Ospreys, Toulon and Bath, while he was also part of the British and Irish Lions squad that toured New Zealand in 2005.
