Lust

Lust
Lust, if not managed properly, can subvert propriety.

German philosopher Schopenhauer wrote:

"Lust is the ultimate goal of almost all human endeavour, exerts an adverse influence on the most important affairs, interrupts the most serious business, sometimes for a while confuses even the greatest minds, does not hesitate with its trumpery to disrupt the negotiations of statesmen and the research of scholars, has the knack of slipping its love-letters and ringlets even into ministerial portfolios and philosophical manuscripts".

Dante defined lust as the disordered love for individuals It is generally thought to be the least serious capital sin as it is an abuse of a faculty that humans share with animals, and sins of the flesh are less grievous than spiritual sins.

In Dante's Purgatorio, the penitent walks within flames to purge himself of lustful thoughts and feelings. In Dante's Inferno, unforgiven souls of the sin of lust are blown about in restless hurricane-like winds symbolic of their own lack of self-control to their lustful passions in earthly life.

Fornication
Fornication is generally consensual sexual intercourse between two people not married to each other.The significance of sexual acts to which the term is applied varies between religions, societies and cultures. In modern usage, the term is often replaced with a value judgment term like extramarital sex.

Adultery
Adultery (anglicised from Latin adulterium) is extramarital sex that is considered objectionable on social, religious, moral, or legal grounds. Though what sexual activities constitute adultery varies, as well as the social, religious and legal consequences, the concept exists in many cultures and is similar in Islam, Christianity and Judaism.[1] A single act of sexual intercourse is generally sufficient to constitute adultery, and a more long-term sexual relationship is sometimes referred to as an affair.

Rape
Rape is a type of sexual assault usually involving sexual intercourse or other forms of sexual penetration carried out against a person without that person's consent. The act may be carried out by physical force, coercion, abuse of authority or against a person who is incapable of giving valid consent, such as one who is unconscious, incapacitated, has an intellectual disability or is below the legal age of consent.[1][2][3] The term rape is sometimes used interchangeably with the term sexual assault.[4]

Bestiality
Zoophilia is a paraphilia involving a sexual fixation on non-human animals. Bestiality is cross-species sexual activity between human and non-human animals. The terms are often used interchangeably, but some researchers make a distinction between the attraction (zoophilia) and the act (bestiality).[1]

Although sex with animals is not outlawed in some countries, in most countries, bestiality is illegal under animal abuse laws or laws dealing with crimes against nature.
