If I could hazard a guess, that would be exactly the type of person I would try to avoid having sex with if I was about to unleash 250,000 pages of state secrets that would make every world government target me as their next most-wanted criminal.
The 39-year-old Australian has denied any charges of misconduct, and he hasn't actually been convicted of anything yet. Assange has turned himself in only because he's wanted as a witness to the charges, and British magistrates will decide whether to extradite him to Sweden if they believe there is grounds to do so.
Regardless, it's amazing that this international criminal could be brought to his knees over personal failings. Assange may go down because he is as loose with his sexuality as he is with top-secret information.
