Journal of Sexual Medicine reports that having sex with animals could give you penis cancer.
The authors found that men who have had sex with animals were twice as likely to develop penile cancer as those who stick with their own kind.
Urologist Stenio de Cassio Zequi, a , gave Live Science his theory explaining the increased risk.
“We think that the intense and long-term SWA [sex with animals] practice could produce micro-traumas in the human penile tissue,” Zequi said. “The genital mucus membranes of animals could have different characteristics from human genitalia, and the animals’ secretions are probably different from human fluids. Perhaps animal tissues are less soft than ours, and non-human secretions would be toxic for us.”
A female member of Equality For All, a pro-zoophilia group, told The Huffington Post that the results of the study should prompt people to take precautions, like using a condom, when having sex with animals, but she said it likely would not deter diehard zoophiles.
A new study has found that 35 per cent of men from rural Brazil have had sex with an animal.
A total of 492 men took part in the study ranging in age from 18 to 80 years old.
The subjects reported a variety of frequencies for their sex acts, ranging from monthly to daily.
The researchers found no association between penile cancer and the number of animals the men used over time. The species included mares, cows, pigs and chickens, among other animals.
A team of urologists from centres around Brazil were involved in the research project, which looked at risk factors for penile cancer in men.
“Expecting people who truly love animals to give up their sexuality and nature just because of some physical dangers would be as absurd as expecting gays to become straight because of AIDS,” Sallie Graves wrote in an email.
“They might become more cautious … but they wouldn’t change their nature. A true zoophile can’t change their attraction and love just because of a higher or lower infection risk.”
Graves also emphasized that E.F.A. sees inter-species sex as benign. She also notes that she’s against causing physical pain to animals and that those who insist sex with animals is inherently abusive are wrong.
“How in the world can I be abusing my dog if I get on my hands and knees and he licks and humps me without me even having to ask for it?”
Zequi’s study is based on a questionnaire about personal and sexual habits completed by 118 penile cancer patients and 374 healthy men recruited between 2009 and 2010.
Additionally, the research found that people who said they have had sex with animals also reported more venereal diseases.
