The 23-year-old Victoria`s Secret model - who married 29-year-old tennis star Andy Roddick, 29, in April 2009 - believes guys in their twenties can be too egotistical and demanding.
She said: "In their twenties men just want, want, want, want, want.
"Don`t make everybody deal with your want all the time. It gets so old. You know?
"After 25, it`s just throw the ego out the door."
The blonde beauty also called for men to stop playing games in relationships and be honest about their feelings.
She told the February edition of America`s Esquire magazine: "Men need to learn to put everything on the table. Just put everything on the table. And when it comes to the game playing, enough."
Though Brooklyn was named by the publication as the Sexiest Woman Alive last year, she admits she wasn`t always so glamorous.
She recalled: "I was 11 years old, and very hairy. After playing in a soccer game, my mom came up and saw my long blonde leg hairs glistening in the sun and said `OK honey, it`s time.` She was right there with me. We got a special fool-proof razor, and fancy shaving cream but I was only allowed to shave up to my knees!"
