Why do humans get so many types of sexually transmitted diseases whereas animals get none?

When you think about it, humans are absolutely filthy when it comes to s*x. The percentages of folks with herpes are so very high. And then you have all of the others: gonorrhea, chlamydia, syphilis, genital warts, crabs, AIDS, Hepatitis C, etc, etc, etc. Why do humans get so many sexually transmitted diseases whereas animals get none?
