Morgan Spurlock has confessed to a history of sexual misconduct, saying he is a "part of the problem".

The Hollywood director and producer took to social media on Wednesday, 13 December to say he is "not some innocent bystander" after witnessing "hero after hero" fall to sexual misconduct allegations triggered by the Harvey Weinstein scandal.

"I don't sit by and wonder 'who will be next?' I wonder, 'when will they come for me?" the Super Size Me director wrote in a Twitter post.

"If I'm going truly represent myself as someone who has built a career on finding the truth, then it's time for me to be truthful as well," he added.

The 47-year-old went on to say that he has been accused of rape by a woman he had a one night stand with when in college. He came to know about the allegations after a friend told him that the woman had revealed their sexual encounter in a short story writing class. No charges and investigation were carried out, Spurlock said.

"That's not what happened!" I told her. This wasn't how I remembered it at all. In my mind, we'd been drinking all night and went back to my room. We began fooling around, she pushed me off, then we laid in the bed and talked and laughed some more, and then began fooling around again. We took off our clothes. She said she didn't want to have sex, so we laid together, and talked, and kissed, and laughed, and then we started having sex," he said.

He added, "'Light Bright,' she said. 'What?' 'Light bright'. "That kids toy, that's all I can see and think about,' she said ... and then she started to cry. I didn't know what to do. We stopped having sex and I rolled beside her. I tried to comfort her. To make her feel better. I thought I was doing ok, I believed she was feeling better. She believed she was raped. That's why I'm part of the problem."

Spurlock also revealed he settled a sexual harassment allegation with a co-worker after she threatened to reveal his treatment towards her at the office. He said the harassment was as bad even though he did not grope the women. He said he paid the woman for her silence so he "could remain who I was".

Spurlock also talked about not being loyal to his former wives and girlfriend despite proclaiming his love for them. "I hurt them. And I hate it. But it didn't make me stop. The worst part is, I'm someone who consistently hurts those closest to me," he said (click here to read the full statement).

While trying to give an explanation for his behaviour, he revealed he was sexually abused as a boy and in his teenage years. He added that he had not "been sober for more than a week in 30 years".
