Lees is the only member of the Owls squad to be a mainstay in the side's starting line-up this season, with Carlos Carvalhal tending to tinker with his line-up.
But Lees is not worried about fatigue, as he is keen to chalk up as many games as possible throughout his career.
“I want to play as many games as I can," he said.
“In my career, it was always a target after I came out of the youth system that I want to see how many games I can play. I have chalked up quite a few so far.
“When I was young, I made the effort to go out on loan so I was playing games straight away.
“I just want to keep playing. If you keep playing, you must be doing something right so hopefully I can keep my place because we have got good players in each position.”
Lees has become a key player for Wednesday ever since arriving from Leeds United in the summer of 2014.
Lees was deemed surplus to requirements at Elland Road, but he has quickly proved his old club wrong with his consistent excellence at Hillsborough.
The 24-year-old was one of Wednesday's most important players last season, and his performances have only improved so far this term.
Lees has helped to guide Wednesday into ninth place in the Championship table, with the side unbeaten in their last five games in all competitions and now just four points adrift of the play-off spots.
