Homosexuality is romantic attraction, sexual attraction or sexual behavior between members of the same sex or gender. As a sexual orientation, homosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" primarily or exclusively to people of the same sex.

Homosexual orientation defe.
-A homosexual orientation refers to the sexual attraction of a person toward members of the same sex. IT is distinct from mere effeminate tendencies in some males or masculine tendencies in some females because these tendencies do not necessarily indicate a person’s sexual orientation

Homosexual act defe.
-A homosexual act, on the other hand. Refers to having sexual relations with another person of the same sex.

Also, look at this verse I found in the bible.
1 Corinthians 6:9-10
“Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God”
