What is the first ejaculation usually like? This may sound crazy, but I used to be so upset that I couldn't ejaculate. I was sad for about 50 days, but I really don't care anymore. I can't even remember the last time I masturbated.
If you recall the orgasm that you experienced when you masturbated without ejaculating semen, then when you are able to ejaculate semen, you will feel something similar, but it will be far more intense. You will also find that the days prior will feel odd to you. There will be an increasing urge, unlike anything you experienced before that you won't recognize at first. Only after you have your ejaculation and the urge disappears for a while will you realize that it was there and what it was. Once it starts you are going to find yourself in a cycle for the rest of your life of a strong, growing urge, followed by ejaculation and relief, only for it to start building up again.
