CMV: I should resist my homosexuality and not lead a homosexual lifestyle

I'm gay and was raised Catholic. I've never been in a relationship (I'm only 18, so maybe not that far behind by gay standards) nor have I ever had sex. 

I don't see any way to lead a gay lifestyle that doesn't contradict my faith. I want to, but I don't. It is against the Natural Law to engage in sexual intercourse that does not serve the purpose of procreation, and to do so would be a direct refusal to "Go forth and be fruitful". Sex, according to the Church, is supposed to be done with the purpose of having children, anything otherwise is selfish and lustful. 

I understand that being gay and having same sex attractions is not sinful, but if I were to act on them I would be committing mortal sins. The only way I can see myself, in good conscience, willfully act on these urges is if I were to abandon my faith, and I don't want to do that.

This isn't something that we can easily change for you. You have a choice to either be honest to yourself or honest to your church. 

That's a decision you have to make. What you have aren't urges. This is a part of who you are and it will not change, not even after you have a wife and children. Would you be willing to lie about your love towards your wife (because you don't truly feel that way about her)?
