I think what you are trying to decide is if temptation will cause you to go to Hell. No, it won't. Everyone who's ever lived has been tempted at one point, including Jesus. However, if we act on our temptations, then yes we sin. Every sin can cause you to go to Hell. Yet, at the same time, every sin, except one can be forgiven by Christ, and that is blaspheming the Holy Spirit. The way we are forgiven is by asking Christ to forgive us of sins and save us. Once we are saved, we are forgiven for our sins, completely and forever. (Understand, this does not give us leeway to continue to sin.)
Once we are saved, we free from the powers of Sin, that means, we no longer have to sin, but instead, can run to God for help. When we have temptations that relate to things from our past, it does not mean that we are demon possessed. Instead, it's simply Satan trying to attack us, to cause us to stumble. One of the greatest founders of the Christian Faith, Paul, even had to fight sin:
"13 Has then what is good become death to me? Certainly not! But sin, that it might appear sin, was producing death in me through what is good, so that sin through the commandment might become exceedingly sinful. 14 For we know that the law is spiritual, but I am carnal, sold under sin. 15 For what I am doing, I do not understand. For what I will to do, that I do not practice; but what I hate, that I do. 16 If, then, I do what I will not to do, I agree with the law that it is good. 17 But now, it is no longer I who do it, but sin that dwells in me. 18 For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find. 19 For the good that I will to do, I do not do; but the evil I will not to do, that I practice. 20 Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me." Romans 7:13-20
The way we conquer him is by letting Christ battle him through us. In other words, let God take over our lives. How we do this is by getting into God's Word. Feeling our minds up with things that are Holy: "Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things" Philippians 4:8
So, chances are, Satan will throw homosexuality up in your face all your life. However, over time, it will be easier and easier to resist the temptations, as long as you fight it in Christ. It's just like an alcoholic. At first, they struggle with not drinking, but over the years, it becomes easier. However, if they let themselves slip even a little, then they are right back where they started.
I hope this helps.
Just be who you are regardless of what people think or say! Good luck with what ever path you decide to take man
