ANSWER: It should first be noted that the KJV Bible does not use the word gay in its text. The word itself comes from the Middle English word "gai" which came into existence around 1275 to 1325 A.D. (dictionary.com). It originally meant something that was fast, sudden, merry or showy. The use of the word gay as a synonym for a homosexual began sometime around the late 1930s and 40s.
Your question about being gay, especially in regard to female homosexuality and what does God say about it, can be found in several places in Scripture. In Romans 1, the Apostle Paul states that women who change the natural use of sex with a man to intercourse between each other (just like men doing so) are in error or sin (verses 26 - 27). God treats both gay males and females the same regarding this behavior and condems all of it.
24. For this cause (people rejecting God exists even though proof of such existence is made plain to them), God also abandoned them to uncleanness through the lusts of their hearts, to disgrace their own bodies between themselves (the gay lifestyle) . . . 26. For this cause, God abandoned them to disgraceful passions; for even their women changed the natural use of sex into that which is contrary to nature . . . (Romans 1:24, 26, HBFV)
In regard to this type of unacceptable behavior, the book of Jude clearly states that all those in Sodom and Gomorrah (men and women) were punished with the death penalty for indulging in "different" or "strange" flesh. This penalty came in the form of fire and brimstone, raining down from heaven upon the two cities, and burning everything up completely like the lake of Fire.
7. Just as Sodom and Gomorrah - and the cities surrounding them, in the same manner as them - having given themselves over to sexual debaucheries, and having gone after different flesh (which can mean practicing the gay lifestyle or even indulging in bestiality), are themselves exhibited as a perpetual example of undergoing the punishment of eternal fire (Jude 7)
Why does God detest homosexual (gay) behavior? Paul, in the book of 1Corinthians (see 1Corinthians 15:42 - 49), reveals that the Eternal is reproducing Himself by creating spiritual sons and daughters. Our ultimate destiny, if we are willing and repent of our sins, is to be a part of the divine family. The purpose of marriage and sex, between a man and a woman, is to produce children that can also ultimately enter the Kingdom of God. A lifestyle that centers around being gay works against this great plan since procreation cannot occur between two people of the same sex.
Homosexuality of any variation is confusion because God ordained reproduction through kind after its kind (Genesis 1). The sexual practices of those who consider themselves gay are against the will of our Creator. It must be stated, however, that although practicing such perverse behavior is a sin, it is NOT the unpardonable sin. Those who repent of their sinful ways will be forgiven by God through Christ.
