I have healthy, unlustful masturbation when I meditate on my seed as Abraham's seed, and see it being planted in the ground to grow a garden, a new paradise for the next generation.  It is good, I find, to avoid masturbation when it is simply playing on loneliness and latent needs and attractions.  Relief can be found in other ways, like a glass of cold, watered down OJ.  

If you can't place yourself among the chosen people, don't beat it.  I'm not sure that's the most Godly attitude, but how will we ever really know?
