There may be nothing specifically relating to masturbation, BUT, there are verses which DO apply to it. (Thanks to one of the members over on my forum for posting this. :) )

One reason that God designed marriage was to alleviate problems of lust. Save your body for the mate whom God will give you:
“Nowfor the matters you wrote about: It is good for a man not to marry. Butsince there is so much immorality, each man should have his own wife,and each woman her own husband. The husband should fulfill his maritalduty to his wife, and likewise the wife to her husband. The wife’s bodydoes not belong to her alone but also to her husband. In the same way,the husband’s body does not belong to him alone but also to his wife.”1 Corinthians 7:1-4

Thinking as God thinks should be our standard. Put evil thoughts aside:
“Letthe wicked forsake his way and the evil man his thoughts. Let him turnto the LORD, and He will have mercy on him, and to our God, for He willfreely pardon. ‘For my thoughts are not your thoughts, neither are yourways my ways,’ declares the LORD.” Isaiah 55:7-8
