There are 9 words used in the New Testament to describe sexual immorality to the reader. In many instances when these words are used, they are used in a sentence together, so one act of immorality could not be confused for another.
For example:

Gal 5:19  Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,

(Here we have adultery listed separate from fornication, uncleanness and lasciviousness.)

1Cor 6:9-10  Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.

(Here we see fornicators listed separate from, adulterers, the effeminate and abusers of themselves with mankind. A fornicator is a man that commits sexual immorality, and adulterer is a person, male or female that commits sexual immortality within a marriage or covenant to God. Effeminate and abusers of themselves with mankind are distinctly different, because they address immorality that goes against the natural design of male and female copulation)

1Tim 1:10  For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;

(Here we see whoremongers/fornicators listed separate from them that defile themselves with mankind. Its considered one thing to commit sexual sin, and another to commit unnatural sexual sin.)

2Cor 12:21  And lest, when I come again, my God will humble me among you, and that I shall bewail many which have sinned already, and have not repented of the uncleanness and fornication and lasciviousness which they have committed.

Eph 5:3  But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints;

Col 3:5  Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil *concupiscence, and covetousness, which is idolatry: (*Lust G1939)

Let’s do a quick recap of the Biblical words presented.

Please understand that my motive for writing this article was not to tell you what I think is considered sexual immorality, but rather to provide YOU with all the tools to do an in depth study for yourselves, and decide what you believe sexual immorality is, based on what the Bible says, and not other people’s opinions.

Now these above words provided are what the New Testament uses in its original Greek. Not words that have been twisted by the hands of men over time, they are the original words used to describe spiritual truths as men were moved by the Holy Spirit to write them. These are not my definitions but rather Thayer and Strong Bible dictionary lexicon definitions.

My earnest prayer is that everyone given these tools would download a bible software and do their own research to find the Truth concerning this topic.

God Bless, Be Free and Set Free!

2 Tim 2:15 Study to SHOW yourself approved of God, a worker that need not be ashamed, rightly dividing the Word of Truth.
