I'll pray.
Try not to think that it's " too hard...because...and because...." because that's just the devil trying to program you. Don't let society program you into thinking that " it's normal and you can't do anything about it". Because that CERTAINLY is NOT true.
Take Jesu for example, He never sinned, He never lusted, and He kept it up all His life ( 33 years! ) this shows and proves to us that with God, the flesh can be conquered, easily, because...if you ask for my solution and oppinion....it's all in the mind, and the mind is more powerful then the body, and the spirit *should* be more powerful than the mind. So, if you get it out of your mind, pray, and work on CONTROLING yourself and CONTROLING the things you think, it should be no problem. It starts by willpower, and if you love God enough ( not blackmailing, just encouraging ), I'm sure you'll be stubborn enough to take control of the lustful desires for two or three weeks, and block them from your mind, you're temptations should, slowly but surely...GO AWAY. It is written: resist the devil and he will flee from you. ".
I used to be into this stuff, badly. I was addicted. And I got rid of it by trying to block my lustful thoughts, and whenever I got a desire, a flashing scene, etc... "I said to myself: " NO! this is not right! ( can add: GREATER IS HE THAT LIVES IN ME THAN HE THAT LIVES IN THE WORLD ), GET OFF me DEVIL, FLESH, SHUT UP AND SILENCE!!! ( or something like that )
Besides, imagine you having a crush on a person, would you like him/her to be into this stuff? If no, well guess, if a person has a crush on you, how he/she'd feel. It's not very comfortable.
" If there is a will there is a way". Just pray about it. These are just my suggestions, I hope they were of any help to you. ^^
But may God lead you to whichever cure He that's right for you. And remember: it's all just in the mind and therefore only half, if at all, as tough as people make it out to be or claim.
Scripture suggestion: Check out Galatians 5:19-22, it may shock you. It did me. O.O;
God bless ya'! I'll deffinately be praying! ^^
BTW: Did you already repent and ask for God to purify your soul and mind? Did you devote your life as much to him as you should? Sometimes people ( including me sometimes ) can forget these things...
