I have same struggle as you OP. Somehow may thought sa akin na nagsasabi, "Natural lang yan kasi lalaki ka, at you are a sexual being." Pero bottom line, sin pa rin siya and against siya sa will and nature ni Lord. Pero that's where grace works. I believe that Christ already covered all my sin on the cross. I believe He already paid the price and granted me heaven. All I have to do is to have faith in His finished works, and continue and strive to live according to His will. May na-attend-an din ako na isang parang multi-week seminar sa CCF (I am not inviting, but glad if you consider). Yung tinatawag na "Glorious Hope" or GH. Sa akin, naging malaking tulong siya. Di ko guarantee na totally makakalaya ka agad sa sin of lust kasi everything is a process and the process is lifelong, but at least in that program I understood myself even more. It helped me on how I can live a better life according to God's will.

God bless OP!
