Hulk Hogan has denied previous claims he has a "10 inch penis", and insisted he was speaking in character when he made the comments.
The former WWE Hall of Famer - whose real name is Terry Bollea - has been giving evidence as he seeks $100million (£70million) in damages from Gawker, who leaked footage of his romp with the wife of his then-best friend , radio shock jock Bubba the Love Sponge.
The court case - which will test celebrity privacy rights and freedom of the press in the digital age - has seen the wrestling star comment on the distinction between his Hulk Hogan character and real life.
"We were discussing Hulk Hogan's... I do not have a 10-inch penis, no I do not, seriously. Terry Bollea’s penis is not 10 inches," he said in court, before being asked by Gawker's attorney Michael Sullivan to clarify if he was discussing "Hulk Hogan's penis".
"Yeah, because Terry Bollea doesn't have a 10-inch penis," he added. "I was in character. I embellished a little bit about the number of women. I was totally Hulk Hogan — I wasn't at home in my private house."
On Tuesday Hogan, 62, was cross-examined by lawyers for New York-based website Gawker.
Gawker's lawyers played videos of Hogan doing interviews with celebrity news website TMZ and radio host Howard Stern about the sex tape.
"I was just trying to make the best out of a bad situation. Howard was making me laugh," Hogan said.
Hogan said that he was in his Hulk Hogan persona when he did the interviews, and made bawdy jokes in character.
"I didn't want to bring Terry Bollea the man, separate the character, in to the conversation," Hogan told the jury.
Gawker's lawyer also pressed Hogan about whether he asked the interviewers to not raise the issue of the sex tape.
Hogan said he did not, that it was his publicist's job.
Although the trial has been full of salacious details - an interview on Tuesday mentioned Hogan's "thong-shaped tan line" that was visible in the video - it is also a serious First Amendment case.
Gawker sees its 2012 post as protected speech under the First Amendment of the US Constitution, and contends it was reporting on a celebrity who publicly discussed his sex life.
Hogan and his lawyers say that Gawker invaded his privacy. He is suing Gawker for £70 million, saying the posting of the video caused him severe emotional distress. If Gawker loses, the media empire could be in serious financial trouble.
Gawker says the publication was a legitimate scoop because Hogan had talked openly about his sex life before, in forums such as Howard Stern's radio show.
The lawyer for the New York-based website says Gawker has a right to address uncomfortable subjects, reject spin by celebrities and tell the truth.
Gawker's reporter, AJ Daulerio, posted the video to accompany a story about how celebrity sex tapes fascinate the public - while being lacklustre.
"Celebrity sex is incredibly dull," Gawker lawyer Michael Berry said.
Mr Berry said Gawker did not make money off the post. Advertisers do not post on Gawker's items that are labelled "NSFW", or "not safe for work".
Mr Berry also said news of the tape, including screen shots, was on other gossip sites before Gawker published the video.
He added that Gawker founder Nick Denton "wants people to know the truth. The simple unvarnished truth".

The trial is expected to last three weeks.
Hogan attained pro wrestling stardom in the 1980s and 1990s, winning multiple championships.
He also became a celebrity outside his "Hulkamania" fan base, appearing in movies and television shows, including a reality show about his life on VH1, Hogan Knows Best.
As Hogan gave evidence, he told the jury about being poor, sleeping in his car while performing in small-town wrestling matches and finally getting his break when he was asked to appear in the third Rocky movie.
During cross-examination, a lawyer for Gawker questioned Hogan about inconsistencies in his evidence and media interviews.
Hogan said he did not watch the video when he discovered its existence but during a media interview he said he did.
And Hogan said he did not know he was being filmed when he had sex with Heather Clem. But in media interviews in 2012, Hogan said he asked Bubba Clem if he was being filmed.
Hogan said the inconsistencies were the result of being shell-shocked by the tape and because he routinely put himself in his wrestling character.
"I was probably in the Hulk Hogan mode," Hogan said. "It gives you artistic ability, to be a character."
