Despite skeptics dismissing Madonna’s boyfriend Jesus Luz as a mere boy toy, it seems the couple is stronger than ever – especially since the 23-year-old model helps keep the pop queen in her eternal quest to feel young.

“For her, the relationship makes her feel good and keeps her young and that is all she cares about besides the children,” sources tell Fox411.

And despite the age difference, the May-December romance works well for the pair.

According to our sources, “Jesus understands Madonna and for all their age difference, they never fight.  They make each other happy and neither one gets jealous when they are apart.  It’s a simple relationship that works for them.”

While Madonna was busy appearing on “The Marriage Ref” recently, Luz was working in Montreal and letting his friends have all the single fun.  While Luz isn’t planning on marrying the pop icon anytime soon, he is eternally committed to their relationship and will not cheat, our sources say.

“Jesus just wrapped a DJ gig in Montreal and he brought along 3 friends.  While he was busy working at Club Unity, they had a fancy dinner at Otto and hung out and did the partying and drinking for him.  Jesus spun his set and quietly set up residence in the penthouse E-WOW suite at the W Montreal.  His biggest splurge was ordering himself room service!”

Friends tell us that Madonna has warned him that marriage is not a big concern to her but they are planning a future together.  Moreover, Luz is happy to play the role of the male figure in their home.

“Jesus has taken on a husband-like role in the household and he spends lots of time with the children,” friends tell us. “He’s an older brother/father figure. They travel together and the family is close.  She loves having him around and he makes her smile all the time.”

And while Madonna likes helping Jesus with his work, the Brazilian stud never asks for anything, nor does he treat her like she is merely a sugar mama.

“He doesn’t take advantage of Madonna and respects her as a partner and friend.  He’s very nice and interested in people, but he has a close circle of friends and he is careful not to divulge anything about Madonna outside the circle.”

Jesus will barely look at other women, let alone flirt with them!  ”When Jesus is out in public, he avoids making eye contact with women on purpose.  He is always friendly, but he will end a conversation with a woman quickly.  Jesus even avoids alcohol, he’ll have a beer but that’s about it.  He knows that eyes are everywhere.”
