An online edition of a New Zealand newspaper recently reported on this new and growing trend.
A group of "vegansexuals" had emerged in the country, where vegans, who abstain from meat or other animal products, would not even get intimate with anyone who was a meat eater.
"It's a whole new thing, I have not come across it before," said Annie Potts, co-director of the New Zealand Centre for Human and Animal Studies at Canterbury University.
She coined the term after doing research on the lives of "cruelty-free consumers".
Potts said that while many female respondents in their survey said that they did not want to have sex with people who eat meat because their bodies were made up of animal carcasses.
One vegan respondent from Christchurch said: "I believe we are what we consume, so I really struggle with bodily fluids, especially sexually."
"I would not want to be intimate with someone whose body is literally made up from the bodies of others who have died for their sustenance," another vegan said.
