I'm doing my best not to live a homosexual life anymore. I pray every night now for God to help me get rid of these thoughts I have towards men but I still do. There is especially one person who I like. We've already have been intimate but after the 2nd time, we decided that we shouldn't be doing this. I don't want to have sex with him anymore because I really do want to go to heaven but since my sexual thoughts are about him, I want to have sex with him. I don't know what to do. In Romans 1:26-27, it says homosexual desires are not natural but I pray every night to God to take this away from me because I do not want this lifestyle at all. I'm trying my best to avoid being with men but I can't control my thoughts about being attracted to them. What can I do? Thank you.
From what you have written it appears that you are sincere in wanting to change. It is also apparent that it is hard. Change is never easy. While homosexuality is not chemically addictive like cigarettes or other drugs, it is a way of thinking that you have developed. That may be more addictive than chemical addictions. We all want to hold onto long established ways of thinking.
I think you are already doing one thing that will help. You are praying. God listens. He may not work on our timetable, and we often interrupt his helping by insisting on doing it our way, but if you persist in prayer that can not but help. You have also helped by agreeing with your partner not to persist in that behavior. If he feels as strongly about it then you can help each other by continuing to refuse each other.
I would also suggest that you go to the Christians No Longer Gay Living For God web site. Since I have not had to deal directly with your particular problem I may not be able to answer you as well as one who has. The founder of that site will be more than happy to answer your question in a way that I can't. He knows your pain, and will answer you.
One other comment, and it is not meant to demean you in any way. You state that your motivation for wanting to quit is that you want to go to heaven, which may be the same as saying you don't want to go to hell. This is a perfectly good and valid motivation, but it is not the strongest one. When your motivation becomes one of love for God rather than just fear of not going to heaven, you will find it easier to follow His way. "There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love." (1 John 4:18) "If you love me you will keep my commandments." (John 14:15) Work on transferring your love to God.
