Channing Tatum's daughter Everly is just three, but the actor has penned a touching letter for her to read during her "teens or early 20s". In the special write-up for the Cosmopolitan, the actor reveals how he wants his daughter to "discover her sexuality" and find her true love.

"I tried to imagine the things I'd want her to read that would help her understand men and sex and partnership better, and at that moment, I realised a strange thing," The Magic Mike actor wrote. "I don't want her looking to the outside world for answers. My highest hope for her is just that she has the fearlessness to always be her authentic self, no matter what she thinks men want her to be."

In his letter, the 37-year-old American actor spoke about his wife Jenna Dewan-Tatum's unerring devotion: "Jenna just blurted out that she knew exactly what she wanted in life and she didn't have to look for it anymore because it was me."

The actor admired his wife for accepting the "good and the bad" of him and confessed that he felt strength because Dewan "accepted every part of me".

"She had no idea what I'd say or how I'd react, but that was her truth. I remember feeling this incredible rush – it was the sexiest thing she'd ever done for me."

Tatum explained the reason that made him fall for the Step Up star and wrote: "That radical authenticity of hers was what made me fall head over heels in love. Before I experienced it, I wouldn't have known how to ask for it. Now I know it's what I was always craving. And that's what I want for my daughter – to be expectation-less with her love and not allow preconceived standards to affect her, to ask herself what she wants and feel empowered enough to act on it."

In his powerful message for his daughter and other young women, Tatum wrote: "If there's one thing that I think men wish women knew, it's just that they alone are enough. When more women start to truly feel this power in themselves, the world will become so magical, it makes my head hurt."
