I just wanna say that I am very very happy that you know that these thoughts being pressed on you are in no way natural, out of your control and just who "you" really are, and are aware that it is in fact the fallen angels on the earth trying to lead you away from God. The fact that you know the truth makes me really happy :3 And also, I want you to know that I am going through the same thing. Something crazy happened to me last year. I was living sinfully, as homosexual and transgender, but God showed me the truth in a crazy and hard for most people to believe kind of way. I have since truly accepted Christ in my heart, and those desires have pretty much left me entirely. But, I still get that unwanted voice in my head that tells me "Im sad, I cant help it, its not fair I cant be the real me". Haha, can you believe it? God has shown me the truth, and shown me the danger I was in because of these desires. And even with this I still have a demon putting those ideas in my head

You are not alone. Know the truth, and know that you cn live an incredibly happy life without fulfilling every desire you ever have put on you.
You are going to be pushed the wrong way by the people of this earth. They will tell you you cant help it, that its just the way you are, and even that God is cruel for not allowing it, and try to make you see things their way. Remember that they dont say this because its true, they say it because they want to fulfill the desire, and want the deception over the truth. I came from this life, and there are many others like me. You can say no to temptation, and no, your life will not come to an end because of it
Stay strong, the enemy will only continue to push you harder and harder as time goes on. right now, its just a curiosity, tomorrow it will try to make you believe you cant help it, and its cruel to you to refuse it. Stay strong with the truth. Ill pray for you :3
