Sleepy God bless you. GOD gave us all a choice and through Jesus Christ's defeating against the devil on the Cross, gave us authority over all sin and tempation.
That means your cousin does have a choice.
Let us not forget this very important passage...
1 Corinthians 6:9
Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders
Some more...
Deuteronomy 23:17
17 No Israelite man or woman is to become a shrine prostitute.
1 Kings 14:24
24 There were even male shrine prostitutes in the land; the people engaged in all the detestable practices of the nations the LORD had driven out before the Israelites.
Leviticus 18:22 (KJV):
Thou shalt not lie with mankind, as with womankind it is abomination.
Leviticus 20:13:
If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them
Romans 1:24-32:
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompense of their error which was meet.
28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
Romans 8:1
There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
6 For to be carnally minded is death; but to be spiritually minded is life and peace.
7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then they that are in the flesh cannot please God.
9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
11 But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
12 Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
Strength through Jesus Chirst:
Philippians 1:6:
Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ.

No one has to live in bondage with an abnormal life of homosexuality nor any other abnormal behavior. No one has to be controlled by pornography. No one has to have evil thoughts plague their minds. There is a way out through what Jesus has done for us. He loves sinners and wants to free us from any evil practices. He will empower those who cry out for deliverance to get free and stay free. Here are the steps you must take to get free:
(1.) Make a total commitment to the Lord Jesus Christ. Be willing to turn your life completely over to the will of God and yield to His plan for your life. This means you must be willing to do anything, go anywhere and give up any thing as He leads. Remember, God will never lead you to do anything that is not in agreement with the Bible. You can trust God. He created you and has a better plan for your life.
(2.) Your must pray and read your Bible daily. You must study and apply the Word of God to overcome Satan's attacks. The way that you resist the attacks of the devil is by quoting the Word of God to him. When the devil came to tempt Jesus, He simply quoted the Word to him. Good praise tapes will also be of a great help when you are tempted. Put one on and start singing along with it.
(3.) You must pray for and seek out a strong Bible believing group of Holy Spirit filled people. You will need their help and fellowship. As you humble yourself and seek help, the Lord will deliver you. Ask God to lead you to someone that can pray the prayer of deliverance for you, as you probably will need to be set free from a demon. You should also seek to be filled with the Holy Spirit as you will need His power to get free and to remain free.
(4.) You must cut off all sources and relationships that would lead you back into sin. The Bible tells us to flee fornication (sexual sins). You must get out of any corrupt entanglements, or areas that you know will be a temptation to you. If you have been hooked on internet pornography subscribe to an Internet Service Provider that will filter out the pornography for you. Destroy all evil books and videos.
(5.) Should you slip or fall back occasionally, repent and get right back up and go on with God. Do not allow the devil to condemn you once you have repented. Put your sin under the blood of Jesus. He will strengthen you and you will win this battle because of the Lord's promise to you. Remember, He loves you and is there to help you. Run to Him when you get in trouble, never run from Him. He will not ever give up on you! We too, will be standing with you for your total healing and deliverance. Philippians 1:6: "Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ."
(6.) You must forgive everyone that has ever hurt you. You can only do this through the power of God. You must by a simple act of your will voice the forgiveness and then the Lord will give you the feeling of forgiveness. This may be a while in coming but just keep forgiving when you think of any wrong that has been done to you. The Lord will give you His love for those people who have wronged you.
