When you think about it, humans are absolutely filthy when it comes to sex. 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? What is it with humans? Why does nature punish humans for having sex whereas animals can have as many sexual partners as they want and not get a disease?
