Mark said the hype surrounding his womanising image got so bad that he begged producers to tone it down.
He continued: "I am so grateful to TOWIE for putting me where I am today, but I did get upset a lot over the way I was portrayed.
"My family and friends, and my sister Jessica, would get upset too.
"I had several discussions with producers about it."
In The Sun's exclusive interview, Mark, 24, also revealed he now can't wait to capitalise on his I'm A Celebrity success.
He said: "I want to act and present. I went to the Sylvia Young acting school for ten years. Acting is the path I want to go down.
"I have a motto, 'Reach for the stars,' so I'll say it. Laugh all you want, but I want to be the next James Bond."
Mark's manager Jonathan Shalit ? who propelled Myleene Klass to stardom after her jungle stint in 2006 ? has been inundated with offers for his client, including fronting an ITV2 spin-off of dating show Take Me Out.
Mark said he'd be up for it, adding: "It sounds like a good show."
Mark found fame on "scripted reality show" TOWIE, which first hit TV screens in October last year.
It follows a group of pals in Essex. Even though it is based on real life, scenes are set up by producers and drama whipped up.
But Mark ? who quit TOWIE just before heading into the jungle ? said it had got too much for him.
"I was on a TV show where they exaggerated people's personalities and choose one side of you that they want you to be," he said.
"My storyline was to be a bit of a ladies' man. But that is just one side of me, an exaggerated version of me.
"That is one reason why I am glad to leave TOWIE as I don't have to be that person I don't like being any more."
Over Mark's three series on the cult ITV2 show, he was seen splitting up with long-term love Lauren Goodger, getting back with her then getting engaged ? before breaking up again.
He also had flings with Lucy Mecklenburgh and Sam Faiers.
After revealing yesterday in The Sun that he was over Lauren, Mark said there was no going back to Sam, who had dumped him in the final TOWIE episode.
He said: "Sam is in the past now. She is a lovely girl but I am looking forward to the future and being single now and trying to crack my career."
He also hit out at former flame Lucy, after she said she didn't want him to become King Of The Jungle. Shaking his head, he said: "Lucy makes mistakes and tries to blame other people."
Mark admitted that playing out his relationships in front of the cameras became too overbearing.
He said: "There is a point in your life when you are filming a show like that where you think enough is enough.
"I have played out my life and my relationships on camera enough now. It is about time for me to go home from work and forget about what has just happened.
"It was hard playing out my life in the public eye for a year and that's why I want to move on from that now."
Mark said he was ecstatic I'm A Celeb had finally let viewers see his proper character.
He added: "I wanted to show people the real me. The real me is what I showed in the jungle.
"My family and friends were relieved because when they see TOWIE they know that is not me. I will never forget TOWIE and the people who gave me the opportunity. It will be in my heart for ever.
"But I just wanted to be real, and however far TOWIE took me, I couldn't do that any more."
Despite reports he is considering one last appearance in the TOWIE Christmas special, Mark said the show is well and truly behind him.
He said: "I won't be in the TOWIE Christmas show. I have moved on.
"Once I have moved on I like to go onwards and upwards.
"I am an ambitious young man, sometimes a bit too driven. But I am also a real family boy.
"I can be a cheeky chap at times but a harmless cheeky chap."
