Firebrand politician Mark Latham has said the mere thought of two men having sex was so 'disgusting' to a straight male it made him want to 'vomit'.
'The basic natural reality is that we don't go for anal sex with blokes and it's pukeworthy,' the One Nation leader told a radio audience on Thursday.
Mr Latham revealed more of his views on homosexual acts when asked to explain an offensive tweet he posted about about gay MP Alex Greenwich last month.
Mr Greenwich had called Mr Latham a 'disgusting human being' for attending a rally where Christians clashed with LGBTQI activists on March 21.
'Disgusting?' Mr Latham responded on Twitter.

'How does that compare with sticking your d*** up a bloke's a*** and covering it with s***?'

Mr Latham, who has refused to apologise for the tweet, appeared on Chris Smith's program on Thursday afternoon and went even further with his comments.
'I speak for a lot of straight men, Chris, in saying that the idea of having anal sex with another man would make you vomit,' he said. 'That's what makes us straight.
'Now, Video Porn Bay I know there's no category or letter in the LGBT ABC WTF alphabet for straight men but that's how we honestly feel about people like Greenwich.'
When Smith asked Mr Latham if he would use the same crude language in the tweet if he had his time over again he said: 'Well, it's code for anal sex between blokes'.
'I can tell you, Chris, if someone held a gun to my head and said I had to have anal sex with a bloke I'd vomit.

I'd vomit all over him. And I speak for straight men and this is what makes us straight.'
One Nation founder and federal leader Pauline Hanson called on Mr Latham to apologise after the tweet but he said on Thursday he would not. 
'Pauline hasn't rung me at any stage during this,' Mr Latham told Smith.

'I've had no contact from her whatsoever. 
'I'm assuming that as a woman she doesn't understand how straight men feel about this and... gay men obviously wouldn't understand how straight men feel about it but it's true.

'It's an absolute fact integral to our existence. It's not confected outrage or a confected point of view. We find the thought of having anal sex with another man to be off-putting, disgusting, horrible - you know, vomit-worthy. 
'So, you know, that's just the reality.
And that's not homophobia, that's just nature. 
'The basic natural reality is that we don't go for anal sex with blokes and it's pukeworthy.'
Two days after his original social media outburst, Mr Latham explained his refusal to apologise for the now-deleted tweet about Mr Greenwich.
'Sometimes in public life when you throw out insults they come back at you harder and truer … So boo-hoo Alex Greenwich,' he said.
Mr Latham said that when Mr Greenwich 'calls someone a disgusting human being for attending a meeting in a church hall, maybe attention will turn to some of his habits.'
'Greenwich goes into schools talking to kids about being gay,' he said. 'I didn't want to be accused of anything similar, leaving that kind of content on my socials.'

NSW Premier Chris Minns previously called Mr Latham's tweet 'vile' and said on April 2 he would try to block him from chairing any committees in the NSW Parliament's Upper House. 
Mr Latham responded to that call by telling Daily Mail Australia he was 'not running for any' committee chair positions and describing Mr Minns as 'a fool'.
On Thursday, Mr Latham told Smith his tweet had been justified by Mr Greenwich suggesting he had encouraged violence at the the LGBTQI rally. 
'Greenwich went out there and said I was a dangerous person,' he said.

'Said that I'd incited the violence, said that I was a disgusting human being.'
Mr Latham said being called a disgusting human being was 'probably as extreme as you can get' for a politician and father.
'I took it to be an attack on my love of my children, my role in my community, my work in public life,' he said.
'He's attacked my very existence as a human being as disgusting. 
'Greenwich has gone way over the top without any facts and I said what I honestly believe to be the truth in response to him. I gave my opinion. 
'It's not an opinion that's fashionable, obviously.

It was crudely expressed. The crude words were taken down off Twitter but there'll be no apology for Greenwich.'

Asked what he would do if Ms Hanson demanded he resign from her party Mr Latham said: 'Well, she hasn't contacted me and I'm not apologising'.
'So I'm not resigning from anything.

I'm not apologising and I'm not backing down.'
Given another chance to say he should have expressed his tweet in a different manner Mr Latham admitted he could have phrased it less crudely. 
'I suppose I would have spoken about "anal sex" but that's what I was talking about,' he told Smith. 
'I grew up in Green Valley mate so saying that some bloke's sticking his d*** up some other bloke's bum or a*** is not uncommon in the language. 
'It was very direct langue from the streets.

It was too crude to leave up there, it came down but yeah, I should not have spoken about anal sex. But is that the big problem here?'
The attack on Mr Greenwich briefly brought him to tears, he said.
'This has obviously been hurtful for me.
I had a bit of a cry late yesterday at the end of the day,' he told reporters on March 31.
'After being in this gig for a decade and getting re-elected, I didn't think I'd still be subjected to homophobic abuse.'
However, Mr Greenwich refused to call for Mr Latham to apologise or resign.
'I don't want to give him another soapbox for him to pretend to be a victim when he seeks to victimise people,' he said.
