Masterbation and erectile issues

I understand that masterbation can effect sexual performance in a number of ways from ED, PE, and desire. When I was younger and masterbated a lot, the tremendous release of energy when I masterbated, made me not want to have sex again for a while. When I was lucky enough to fially"score" I would usually have PE. or ED if I had to put on a rubber. Now I am married for 33 year and have had issues, as being older, the frequency and desire to have sex has dropped in me and my wife. It is usually 1-2 weeks apart. lately she has not been feeling well and is putting me off to about 3 weeks. I masterbated yesterday but not to the point of finishing in case she is "ready" today. It is making me want to have sex more (of course), but is this, what I hear the young ones on here talking about, edging, and will it help with, ED, PE, and libito. I am new to this subject and was looking for someone who knows how this works.
