Critics have suggested Gatland should have taken three No10s for the 10-match tour but the coach charged with leading The Lions to series success Down Under wants his main men to have plenty of game time under their belts prior to the international opener in Brisbane on June 22.
It's a sentiment that Sexton agrees wholeheartedly with, especially he recently spent two months on the sidelines after suffering a hamstring injury in Ireland's defeat to England on February 10.
"As a No10, the more game-time I get the better in terms of getting to know the other guys and the game-plan in what is one of the most important positions in the team," said Sexton.
"I won't be complaining if I'm asked to double up and play back-to-back matches. As far as I'm concerned, the more time on the pitch the better.
"You want to cherish every moment of playing in a Lions jersey so I won't be complaining.
"It feels strange to be so fresh at this time of the year because usually I'm pretty knackered.
"I had two months off playing but I feel great. I'm starting to get a bit of match fitness and, hopefully, my match sharpness back. I hope I peak at the right time with these two finals for Leinster coming up."
Sexton certainly has a busy summer ahead as Leinster attempt to claim European and domestic silverware prior to The Lions' departure for Hong Kong on May 27.
The 27-year-old will be looking to fire the Heineken Cup holders to Amlin Challenge Cup glory against Stade Francais at the RDS tomorrow night before he makes his final appearance in Leinster colours when Ulster arrive at the same venue for the RaboDirect PRO12 showpiece a week on Saturday.
Sexton admits that the worry of picking up an injury over the next nine days is a real one but that such thoughts will be a million miles from his mind once the whistle blows for kick off in Dublin.
"Since the squad has been picked, at the back of the mind you're praying that it doesn't happen," added Sexton, who insists two huge provincial fixture will help prepare him for the intense nature of what will follow Down Under.
"But once you get out on the pitch your competitiveness comes through and it is the last thing you think about.
"It is about winning and there are two finals with Leinster, it isn't like they are friendlies. Two competitive games, high pressure, they are the sorts of preparation you want."

Sexton's commitments with Leinster mean he is unlikely to start The Lions' tour opener with the Barbarians on June 1, with Gatland expected to ask England's Owen Farrell to steer the ship in Hong Kong.
But while he admits that Farrell's presence at this week's training camp in Wales and next week's gathering in Ireland gives the Saracens star an early advantage, he insists he is looking forward to not only challenging the 21-year-old for a Test spot but also building the kind of relationship that will ultimately aid The Lions' chances of returning home victorious.
"Owen's a resilient character, he's a great player. They were pretty tough conditions that day when England beat us this year but he kicked his goals and England toughed out a victory.
"Myself, Owen and the other kickers will spend a lot of time on kicking practice after training and 'm sure we will build up a relationship quite quickly.
"He's going to have a head-start because he will have two extra weeks of preparation and might have played in the first game but I can't worry about that - I've got two finals to think about first! I will worry about it when I get on the aeroplane with The Lions."
