I too, jerk to gherkin.
I'm totally against repressing sexuality, but I have noticed a drop in energetic "fullness" after a one hander.
I'm past the "right or wrong" stage that most guys face.
When you really strip it down past all the cultures and dogmas that have plagued masturbation there really is nothing wrong with the practice. When you really think about it there is nothing right about it either. Nature (or God) created animals and human animals, both have gay sex and pleasure themselves, regardless of human cultural ideals. Masturbation is just there. You can do it or not, it is your choice.
You should figure out why YOU choose to masturbate. Find out just why its such a need for you. How does it serve you? It is for sexual release? Or is it to space yourself out in a subtle way? I think they both boil down to the same thing. (Don't tell me you do it for the quoted health benefits or I'm going to have to smack you through your screen)
Does it make you a better person? If so, then wank away son.
If you find yourself more motivated to be all you can be when you don't slap the one-eyed snake, then you shouldn't. I'm one of the latter case, so I'm joining the 30day challenge here a little late. I think in the last few years the longest I've ever gone without jerking off is 20 days. I didn't succumb to sexual desire(read: I couldn't find a girlfriend), I caved and numbed myself through self gratification.
Wet dreams and unconscious lusting don't count unless you are a lucid dreamer
