Need Help/Advise About A Habit

It's weird how I started masturbating, a it before I knew what babies came from and such. I was just relaxing as a little boy and as something touched my body parts, it felt different so i kept doing it and enjoyed the different feeling and began to like it. Well, as I got older, the body part started doing something different and i realized about babies and intercourse. Then even by then it was basically in the long years where i literally had free time 24/7 from no house work or even school. So i did it every day for something to do that was fun. I had no thoughts about women then or sexual stuff, as i did it, i thought about childish video games, eating, the dream i had this morning, what i will do tomorrow, just normal stuff. But as i became close to an adult, i started seeing attractive women, other guys started showing me things of womens bodies, and then i was unsaved and i even started drawing them and naturally it just became an interest as i did masturbation. After i got saved, i didnt like to see women im not married to, or have lust on flesh, but after doing it more than half my life, its addictive or a habit and i can do it without thinking of a womans body or anything sexual, but now i wonder...is it wrong for the action? sinful? is it wrong for the sexual thoughts? both? and sometimes i even wake up from being asleep with the body stuff on the bed, have i sinned? ive prayed about this, because i dont see sin really because i dont have a wife, i feel if i had one then i wouldnt care to do it because i could have her to be with in those times. and i dont see anything changing or being wrong that effects the rest of me or others. So, its not really showing me if its sinful, yet i have ideas why it could, but im trying to be sure, and if it is, i just want to stop. but if it isnt i guess i would just do as i was, just not being lustful.
