With my response, please realize that I'm not trying to push my beliefs or point of view on to you. Abstinence- because I don't have kids, have never been married and am waiting for marriage. In the event that I do ever get married, I don't not want to rob my future wife of any experiences that I squandered elsewhere.
I'm personally opposed to masturbation/self ejaculation as it's not good for me physically, mentally or spiritually. I'm one of those guys whose potential gains were never realized because I couldn't control myself during or after a p.e. workout. If I have ejaculated before I hit the gym, I simply cannot train as hard or efficiently as I need and want to, which also mentally bothers me. With an ejaculation, my testosterone drops significantly, which really hampers my energy levels. Masturbation is self defeating for me and spiritually, is a barrier between me and God, which is something I do not want.
Having not ejaculated in 16 days now, I'm feeling better all the way around and haven't blown any potential gains. The visual temptations are there from women that I see in the store or at the gym, but defeating temptations builds character and helps make a man a man.
