In fact, the American is going out of his way to make sure nobody is able to comment on his sex life.

The move comes amid the US government’s current legal stoush with Armstrong, a $A130 million civil fraud case.

The federal government wanted to know whether Stephanie Mcllvain, a previous representative for Oakley, one of Armstrong’s former sponsors, had engaged in a sexual relationship with the now 43-year-old.

Following this, the man who had seven Tour de France titles stripped from him for doping asked his legal representatives to confirm that the US government would not ask Armstrong or any other witnesses similar questions.

When the government refused to bow to this request, Armstrong’s legal team went to the court in an effort to prevent this line of questioning being pursued in the future.

“Such questions are irrelevant, designed only to embarrass or annoy, and ought to be forbidden,” said Armstrong’s attorneys.

However, the government is arguing that their questions are necessary in order to establish if Mcllvain may have been biased when giving testimony as a key witness in the Armstrong case.

Teammate of the former cyclist Frankie Andreu and his wife Betsy were in a hospital room with Mcllvain and Armstrong in 1996 when they claim the former champion admitted to his doctor that he had taken performance-enhancing drugs.

Mcllvain maintained she could not remember any such incident, and because the Andreus’ testimony could not be corroborated, Armstrong was able to continue to protest his innocence.

The government is pursuing its’ fraud case against the disgraced athlete on behalf of the US Postal Service, Armstrong’s former racing team, who argue they never would have paid nearly $40 million in sponsorship had they known he was doping.
