If you are doing it well, there will come a point when you begin to feel an incredible tension, energy or heat in your pelvis which becomes increasingly intense. It might feel as if you are going to urinate, but don't worry, this is just the feeling of the semen entering the urethra (the tube which runs inside the penis). Don't stop! Keep holding and stroking and just enjoy the sensation. Once ejaculation starts, holding back at the wrong moment can be rather uncomfortable. If the pleasure starts to get a bit too intense, go more slowly or more gently.
When you reach the moment just before ejaculation, the muscles of your body begin to harden, the expression on your face will probably change, and at that moment there will be a series of contractions in your pelvic muscles. At the same time, you will feel a tingling and trembling throughout your body. You might cry out or moan involuntarily. A teaspoonful or two of semen (white or yellowish fluid) will come out of your penis. It might just drip out, but if you are 14 or older it could shoot out with more force, sometimes 30 centimeters. From 3 to 8 spurts will happen quickly, but don't worry - you will feel better than ever before! After 5 or 10 seconds, semen will stop flowing and you will come back to earth! Your penis will probably become very sensitive, so that you won't want to go on rubbing it, and soon you will feel less aroused.
