And please, stop asking me to define perfectly simple words like natural or unnatural. If your high school English teachers didn't do their jobs properly, that ain't my problem. Ta ta.

Right, the meaning of the words "natural" and "unnatural" is
so clear, the only problem are HIM's English teachers...
Let's look at some examples of the use of the word "unnatural", found by a simple Google search. (Apologies to everybody for some of the rubbish you will read here.)
I'll start with a few pages related to this discussion:

The moral case against contraception
Condom
Those who say contraception is morally wrong do so for a variety of reasons.
Contraception is inherently wrong
Contraception is unnatural
Contraception is anti-life
Contraception is a form of abortion
Contraception separates sex from reproduction
Contraception brings bad consequences
Contraception carries health risks
The "contraceptive culture" is dangerous
Contraception prevents potential human beings being conceived
Contraception prevents people who might benefit humanity from being born
Contraception can be used as a eugenic tool
Contraception is often misused in mass population control programmes in a racist way
Mass population control programmes can be a form of cultural imperialism or a misuse of power
Contraception may lead to depopulation
This sounds odd to an age concerned about over population but for substantial parts of the last 150 years this was a real fear.
Contraception leads to "immoral behaviour"
Contraception makes it easier for people to have sex outside marriage
Contraception leads to widespread sexual immorality
Contraception allows people (even married people) to have sex purely for enjoyment

No ‘Unnatural’ Sex Please, We Are Indians!

Indo-Asian News Service
New Delhi—Sexually adventurous Indians may be unwittingly committing several crimes in the bedroom, including some punishable with life imprisonment.
If the Government has its way, homosexuality, oral sex and anal sex, which are increasingly an accepted form of sexual behaviour in many parts of the world, will not be legalised in India just yet.
The Government’s contention in a court that homosexuality should not be legalised as it was not accepted by Indian society has outraged not only the gay community but many who believe the state should keep out of the bedroom.
The Government was responding this week to a petition questioning Section 377 of the Indian Penal Code (IPC) that deems “voluntary sex against the order of nature with any man, woman or animal” a criminal offence to be punished with imprisonment for life or up to 10 years.
“We expected nothing better from this Government than the old bogey of Indian culture and society that is completely divorced from scientific realities,” Aditya Bandopadhyay, a member of the Lawyers’ Collective HIV/AIDS unit that formulated the petition for the NGO Naz foundation, said.
“How can you criminalise a whole community when it is scientifically, sociologically, anthropologically and historically accepted that homosexuality is not a depravity or an aberration?”
The petition, filed in 2001, argued that consenting homosexual acts should be legalized because the fear of arrest and harassment from the police had driven gay people underground, hampering the anti-AIDS campaign.
Responding after a long time, the Government told the court that Indian society was “intolerant” towards homosexuality and repealing the law would “open the floodgates of delinquent behaviour”.
It was argued that this was the only law against child abuse and male rape.
But Bandopadhyay retorted, “Why not frame separate laws for child abuse and male rape? Anyhow homosexuals and victims of male rape are harassed by the police.”
The Section under consideration also bans acts such as oral sex and anal sex that could be described as “unnatural” since they were not “penal-vaginal”.
Said Sarah Fernandes, a students’ counsellor, “Is this a police state? Why should the Government decide how or who do I have sex with?”
Echoing the indignation, bank executive Yogesh Mishra said the law could not dictate what consenting adults did in their bedrooms.
“People have the right to choose their sexual behaviour. In a progressive society, such a law is redundant and should be dumped post-haste.”
The petition said the sodomy law was at cross-purposes with the fundamental right to life and liberty.
“The Government’s view is shocking and effectively means sex should be only for procreation, not pleasure,” said Lok Prakash, technical consultant with the Naz Foundation International.
Stating that this attitude was detrimental even to heterosexuals, Prakash remarked that, legally, even a husband and wife could not have anything but conventional sex.
This is a strange irony for the land that produced the most ancient treatise on sex, the Kamasutra of Vatsayana, and the renowned Khajuraho temples that depict most explicit, and no-holds-barred acts of lovemaking.
Noted sexologist Prakash Kothari refers to instances of homosexuality, premarital sex and alternative sexual behaviour in Indian mythology as well as scriptures.
“It is true that many acts are not accepted by society today, but between mutually consenting adults, oral sex etc are acceptable sexual behaviour,” he said.
“There is nothing like unnatural sex between adults—only alternative sex.”
Kothari pointed out that it was better to have homosexuals satisfying their relationship in their own way than becoming “destructive heterosexuals”.
“Laws are meant for citizens’ comfort and not discomfort. Under the present scenario, IPC Section 377 needs to be abolished.”

Abortion is unnatural
I was 19 and engaged, but really wasn’t prepared to hear the words, "Your test was positive". I was really stunned and numb, so it was really easy to listen to the advice of others. I wasn’t required to really think about my decision to abort. A family member was getting appointments for me, etc.
[The abortion was] really painful, frightening, emotionally drawing. I had guilt and feelings of great loss.
I talked to my baby with a lot of tears, and then asked him to forgive me. The real comfort came when I felt true forgiveness from God and was able to forgive myself. I guess first I confronted the issue of my abortion and then dealt with it slowly over a period of time.
I am always wondering what my child would have been and done in this life. A part of me is missing. A piece of the puzzle is lost. At least now that I’m involved in pro-life work, pro-abortionists can’t tell me I don’t know anything about abortion.
Abortion is unnatural. Abortion hurts us emotionally and spiritually. The reality of my abortion didn’t hit me until four months later. At that time I saw something about abortion on TV -- that set the spark. I locked myself in the bathroom. I went into a frenzy, crying, sobbing, screaming. I felt such intense emotional pain as I have never experienced. I hurt, but I am thankful for what I saw about abortion on the TV. It was the beginning of my recovery period. It was painful, but at least I could start dealing with what I’d pushed into the back of my brain. I just hope that in my pro-life work, I can help other women who have had abortions or are contemplating abortions.
