When humanity ignores the basics of principles of human biology it is to their peril. Anal intercourse is unnatural because the pathology is not designed for it, nor has it any biological purpose, and therefore it brings about physical, mental, and emotional damage. But also heterosexual intercourse with many and frequent partners spreads diseases and causes emotional damage because I did not design the human body and psyche for it.
HIV/Aids transmission is far more likely by anal intercourse. It is because the anus is not biologically designed for intercourse. I designed the female vagina with thick mucus to protect the vaginal wall, and an acid environment which kills a lot of sperm and the seminal liquid. The wall of the anus, lacking these, is very easily torn in intercourse. Moreover the presence of infected feces in the anal tract adds to the likelihood of the transmission of the HIV/Aids virus.
When humanity deviates from normal sexual behavior, breaking the patterns that I created, specifically as it relates to the proper order of sexual intercourse, perilous consequences are the natural outcome. Disorder, whether spiritual or natural, consequently leads to internal and external chaos, not to mention sickness and diseases. I was not being a whimsical God, when I gave mankind the laws of social interaction in the book Of Leviticus, but instead I was framing humanity within the construct of my protection via obedience to my Holy Word.
Homosexuality is a direct assault upon my creation. It is anti-God, and thus anti-family, and anti-life. No one is born a homosexual. The gay community sincerely to believe the lie that they were born that way, a belief that gives them an expedient justification for their deviant conduct. Godliness and restraint requires genuine effort, whereas, disobedience to my Word is taking the easy road, which leads to eternal damnation. All one need to do is kneel to every craving and inclination, even if their immorality injures themselves as well as others.
