Masturbation cannot be done by a male individual without sexual gratification and that requires impure sexual thought.
Really? When I was a teen I was a once-a-day (on average) kinda guy and was doing so for a couple of years
before I found out that it had anything to do with sex. I thought it was tied to urinating. As a result, sexual thoughts and images (after I found out) actually hindered the process for me.
So don't tell me something I know is not right.
Can you give me chapter and verse to prove that one cannot masturbate without inappropriate thoughts?
The book of Leviticus lists in detail all kinds of sexual behaviors that are sinful and prohibited. Masturbation is not included even obliquely. That is surprising as many of the prohibitions in the Law have to do with the pagan worship practices of Egypt and Canaan. Male masturbation was a widely used religious practice in Egypt and is depicted prominently in many of the hieroglyphs that date from the Israelite captivity there.
The only passage in the bible I have found that speaks to masturbation is Song of Solomon chapter 5. Shulamite masturbates and is called "undefiled."
2 “I was asleep but my heart was awake.
A voice! My beloved was knocking:
‘Open to me, my sister, my darling,
My dove, my perfect one!
For my head is drenched with dew,
My locks with the damp of the night.’
3 “I have taken off my dress,
How can I put it on again?
I have washed my feet,
How can I dirty them again?
4 “My beloved extended his hand by the hole,
And my feelings were aroused
5 “I arose to open to my beloved;
And my hands dripped with myrrh
And my fingers with liquid myrrh
On the handles of the bolt.
If you read in the preceding chapters, myrrh describes the female wetness from sexual arousal.
