Steffens, 26, has been dating the 56-year-old singer since January and likes her maturity and strength, reported the Daily Mirror.
"There is an age gap between me and Madonna but I don't notice it. My girlfriends have always been older than me and that's how I like it. I learn a lot.
"Mum is a big inspiration. She is a fighter, a strong independent woman, and any relationship I've had in the past was mostly with women that are independent and like to have an opinion," he said.
Steffens said he would like to have children with Madonna, who already has daughters Lourdes and Mercy and sons Rocco and David because he wants to be a better father than his was.
"I want to be a dad, it's my goal to have my own family, that's there in the back of my mind all the time," he said.
