A Philadelphia boxer who claimed he was drugged and forced to take part in a gay porn film has admitted to being bisexual and making up the sensational story as a cover-up.

Yusaf Mack, 35, confessed Monday that he was 'fully conscious' during the filming of the explicit video, which shows him having sex with two men.

In an extensive statement, Mack said he is bisexual and apologized for lying about how he came to be involved in the porno.

Last week the dad of ten claimed that after agreeing to take part in a porno featuring women, he was given 'a pill and vodka' upon arriving at the set and his memory blacked out.

The film of Yusaf Mack appeared on the gay porn website DawgPound USA, who called his claims about being drugged preposterous. Mack has since come out as bisexual and admitted he chose to do the porno

The statement, issued to website Towleroad, said: 'This is an issued public apology from my heart. I want to address a few situations with the first being the false claims I made about being drugged during the (DawgPoundUSA.com) film.

'I have never spoke negatively about the company that produced the film although the claim to have been given a drug by someone during set was a lie.

'I was completely aware and fully conscious during the film.'

DawgPoundUSA.com, who posted the footage on their gay porn subscription website, hit back at the 'patently false and preposterous claims' that Mack was drugged during filming.

The site, which features African-American men, told Gawker Friday they were pursuing legal action against Mack.

In his statement, Mack came clear about his sexuality and why he agreed to do the film.

'The second situation, which further explain(s) the first, concerns my lifestyle,' the statement said.

'I did participate in the adult film because at the time I needed money but also because I am a bisexual man.

'Meaning I enjoy safely being intimate with whomever I choose.'

Mack went on to 'address the reason' why he lied:

'My life was completely destroyed once it had been outed that I participated in a gay film. I selfishly tried to cover the truth and remain in denial rather than accept the fact that I was leading a double life secretly.

'After reflecting on the mess I had made I realized that I hurt a lot of my loved ones - and the people I cared about the most were left disappointed and confused. It was unfair and time to come clean.

'I want to say sorry to my children and my ex fiancé, I am so sorry that I was a coward and hid a huge part of my life from you all.

'I'm not looking for sympathy or even understanding, I've kept this secret for a long time.

'It is time to move forward and this is me walking in my truth.

'There are other men and women that are set up in the similar situations and I just hope I can be inspiration to be just be you.

'The extreme taboo and harsh criticism of living a same-sex lifestyle, especially as an African- American male, makes it hard to be completely honest and comfortable within yourself.

'But I had to remember that I am a champ and I can fight and will fight through this.

'I am more than my sexual orientation. To all of my supporters I thank you dearly.'

The 35-year-old claimed he was drugged at an apartment in the Bronx and that the video must have been filmed afterwards. He now admits these claims are untrue

The statement is a major turnaround from the comments made by Mack in the wake of the video surfacing. At the time he was engaged to a woman - although his latest statement, referring to his 'ex-fiance', suggests they may have now split up.

'My whole life, I've been what they call a wh**emonger. I love females,' Mack told Philly.com last week.

'The only time I touch a man is when I'm in the ring fighting.'

He retired from boxing last year after losing a six-round fight to Cory Cummings.

Boxing pundits say he was a promising fighter but hit a bad losing streak before throwing in the towel.

Mack said told Philly.com he was contacted with an offer to do porn on Facebook and said he traveled from Philadelphia to New York one night in June to make the video, believing it would be heterosexual.

However, the video appears to have first been put online in December last year.

The former light heavyweight contender claimed he went to an address in the Bronx, where he said there were naked women walking around.

'I think, ''It's about to go down'',' he told Philly.com. 'I needed a drink or something. They gave me a pill and a shot of vodka.

'I took the pill down with the vodka.'

Mack claimed he had no memory from that point.

The next thing he said he remembers is someone waking him up on a train at 30th street.

He then found $4,500 cash in his pocket, he said.

Mack's face was not covered in the footage and neither are were his distinctive body tattoos, which made him easy to identify.

He also appeared to be a willing participant in the acts that were filmed.

The video was then put up on DawgPound USA, where members pay $24.95 to join the site and then a monthly fee of $19.95.

Mack said he was considering legal action against the site.

'I'm just hurt right now,' he told the website. 'I can't really sleep at night, but I'm getting by.

'Everybody thinks I'm going to hurt myself. I've got to stay strong for my children.'

Mack's children range in age from three to 21

'All my real friends who really know me, know I like females,' Mack added. 'I'm still me.

'You've got to realize that the ones that are not really talking to me are the ones that probably have skeletons in their closets.'

DawgPound USA insisted that Mack knew what he was doing in the film.

In a statement released Friday, a spokesman said: 'DawgPoundUSA.com is a reputable company which has produced high quality videos of men-of-color since 2002. At no time have we ever coerced or drugged any of our models.
