Lots of interesting ideas, questions and things overlooked. self-gratification is proven healthy to a healthy degree and the studies to show for men that it helps in testicular and prostate cancer are for very obvious but again overlooked reasons. Though a side issue for you, important none-the-less. Like every cell in the body, old out, new in. That goes for minerals as one stated though he said you loose to many. The prostate is loaded with zinc, more than any other place in the male body. If you get a decent zinc intake...terrific but common sense tells you that if your diet is devoid of zinc and you spank the monkey daily...things won't end so well. That said..beyojnd the psycho physical is the crucial importance of zinc and if you get too much. Your penis will be like a windsock in a any gust and breeze. Far more than that and always overlooked is histamine. Histamine is what generates ogasm for men and women alike as well as glans penis sensations and erections of penile and clitoral tissue. Conversely, if histamine is low E.D. can become and issue among a host of other serious problems from the heart to the brain. Do you have allergies? 95% of allergies are actually Histamine Intolerance and thats caused from things like wine, alcohol in general, sugar, drugs, corn, fungal mycotoxins (in all our food supply and generally not tested) among others things. Google histamine intolerence. So in my view and experience, self-gratification is great when considering holistic health and as part of a healthy lifestyle with or without a girl. Like the breasts when suckled by a baby and Iodine not replaced or like the ovaries and thryoid when bromides are taken in, they deplete Iodine and if not replaced....cysts, nodules, fibroids and cancer ensue. Get the baby batter out, but be sure to replace those rapidly lost minerals from zinc to cancer killing selenium the prostate is rich in. If you want to lessen the "urge", lessen the vitamins, minerals and intakes that boost them. If you must..eat more soy. That will dip the urge but the estrogen damage may not be worth it. Pick up some new thoughts, reads, hobbies, with confidence and be healthy. Know doubt you will be fine. I am confident in you and that.
