99.9999999 percent of women are not fucking dogs or any other animals. There are far more men fucking animals because men are the ones with libidos, not women. Beastiality porn exists because there are MEN who are into that porn.
Well, that's not true. The lowest record rate for bestiality among women was 0.6% which was a study done on undergraduates back in the late 90's, so girls who are around 18-24. The highest was 3.6% which was conducted by Kinsey in the middle of last century.
The thing about these numbers is that there are also studies done on bestiality using a polygraph test. They asked inmates about engagement with bestiality before and after the test. In one study... "Whereas 37.5percent admitted to bestiality, this increased to 81.2percent when questioned using a polygraph." and in a different study using the same method "While prior to the polygraph investigation only 4.4% had admitted to bestiality, afterwards 36% reported to have engaged in bestiality."
What this tells us is that A) There's never been a recorded rate for bestiality among women that went lower than 0.6% and this was in the late 90's in a study exclusively of undergraduate students who would be around 18-24. All of these rates were record last century, /before/ the explosion of internet porn became available and started influencing people's sexual interests.
B) We know from other studies on porn that women are overwhelmingly more interested in porn that depicts violence against women. Before this came out I'm sure most people thought it was just men watching these videos. Turns out men aren't really all that into it.
C) Even with the rate of bestiality recorded at ~0.6% to 3.6% for women we know from other studies that used polygraph tests that people lie on these questions, and not by an insignificant rate either.
There's a lot more to write on this subject, like other studies that show that women are more sexually fluid (experimental) than men, porn search studies, anecdotal accounts from guys who into watching girls with their dogs, etc. I've talked to a number of guys with dogs who are into this and many of them said that you can talk almost half of the women out their into trying a dog, if you do it in the right way. This is a bit like talking a girl into making out with another girl, some will be into it and others will think it's gross but you'll have a much harder time talking a guy into making out with another guy. Women aren't as sexually normal as you're making them out to be, and guys aren't as sexually adventurous as you suggest even if they have a higher libido.
