In his first season in France the Parisian outfit are currently preparing for the play-offs and Sexton admits that he will definitely stay in France next season and beyond that is up for debate.
"They (Racing) are keen to get talking now and I've said, 'let's wait until the end of the season'," Sexton told the Irish Independent.
"It's a family decision now, we've a baby on the way, me and Laura, and it's very much a case of 'let's see how that goes' - having a kid here and not having grandparents, aunties and uncles to look after it.
"We'll just have to see how that goes for the next few months, all being well, touch wood, we'll see what the options are then.
"You don't make decisions based on one game or two games. From a professional point of view there is still a long way to go, there are still some frustrations and days where it's great and you love it - the lifestyle and stuff.
"There are still things you miss from home. I was home last week and you quickly dip back into that routine, remembering the good old days."
