“I can’t have sex and so the whole thing is impossible,” he told daily Expressen.
The ex-minister, who reportedly was part of a previous government, has been convicted for trying to buy sex from a known prostitute.
He was caught after police saw him pick up the woman in his car in February, where he allegedly negotiated the purchase of oral sex.
The woman got into his car and they drove off, but as the ex-minister felt that he was being followed, he stopped the car early and let her out, reported newspaper Aftonbladet.
Police questioned both and it turned out he had already given the woman the money.
The man, who is said to have had important political duties, was reportedly at one point a strong contender to the post as head of the party he represented.
When he found out he was under suspicion for attempting to purchase sex he confessed straight away and was fined 19,200 kronor ($2,814).
Now, however, he denies all allegations.
“I have prostate cancer and it is treated with hormones, which means the sex drive disappears. I am medically castrated, one could say,” he told Aftonbladet.
Instead, the man claims he was giving the woman a ride home. He said no sexual favours had been discussed.
“I had been out shopping and when I get to the car she asks me where I live. I tell her where I live and she asks if she can come. I was going to drive her home as it was on my way. Then I started driving her home,” the ex-minister told the paper.
The ex-minister claims that he has “tried telling people” but that he has been unsuccessful in getting them to listen. At the time he had felt that he had no other choice than to confess to the officers.
“The police told me that I could choose between the case being taken to court with all the public exposure that would entail or accept an order of summary punishment,” he told the paper.
In retrospect, confessing was probably a mistake, the man said.
“It was a stupid thing to do. Now most people will think I am guilty,” he told Expressen.
