@Smileyrius,
Just to define the word, fornication, I will draw on Wikipedia. Fornication is generally consensual sexual intercourse between two people not married to each other. For many people, the term carries an overtone of moral or religious disapproval, but the significance of sexual acts to which the term is applied varies between religions, societies and cultures. The definition is often disputed. In modern usage, the term is often replaced with a more judgment-neutral term like extramarital sex.
“Bahá'u'lláh, like all the other Prophets and Messengers of God, preaches abstinence, and condemns, in vehement language, all forms of sexual laxity, unbridled licence and lust. The Bahá'í standard of sex morality is thus very high, but it is by no means unreasonably rigid. While free love is condemned, yet marriage is considered as a holy act which every human being should be encouraged, though not forced, to perform. Sex instinct, like all other human instincts, is not necessarily evil. It is a power which, if properly directed, can bring joy and satisfaction to the individual......While the Bahá'ís condemn asceticism and all extreme forms of self-mortification they, at the same time, view with disfavour the current theories of sex ethics in which sex before marriage and outside marriage are allowed. (Shoghi Effendi, The Unfolding Destiny of the British Baha'i Community, 434).
