You sound like me, when I was a Christian.
When I look back, WHEW! What self-imposed misery!
I struggled and struggled to not look at girls in a lustful way - I felt like I had a lust addiction - excess hormones, etc...
I prayed, fasted, controlled my thoughts, etc, etc, etc...
But while in college (studying to become a Christian Apologist) I found out that the Jesus of the bible never existed, and that the Bible Manuscript Tradition was full of corruption and forgery.
So, when I finally allowed myself (after all, all my college friends did it) to actually and willingly look at pornography, I was relieved (pun intended) when I found out that after a little indulgence and after I made it so that I could look at pornography whenever the heck I wanted to -
I found out that after a short while, I just lost interest.!!!
WHAT A SHOCK!
The "LUST" problem I had literally ceased when I no longer saw it as a problem or something BAD!!!
The only time ever "battled" lust was when I was a Christian.
When I was freed of that, NATURE showed the true PATH TO DELIVERANCE.
My friend, your answer, believe it or not, is to look at pornography - make it easily accessible and to have several one night stands.
Eventually, it won't be an issue.
AND you'll become NORMAL!
