Why do I get soft doing ejaculation?

Going to the point of no return is when you ejaculate but not want to yet but if you go to the point where you are real close to ejaculating and stop it's called Edging and I do it every time I jack off. However I don't go into the bath room and jack off, I do it in front of the computer screen looking at some kind of erotica. An orgasm and climax is the same thing and most guys go soft after they have an orgasm but not all guys. Also try jacking off with some baby oil and rub it around on the head of your penis while masturbating and it'll give you a very Intense pleasure, much better than just pumping your penis back and forth.
