I know you’re upset, but hold your horses. There is hope. Premature ejaculation (coming too fast) is quite common in young men. (I assumed you’re young since you said ‘girlfriend ‘not ‘wife. ‘)What causes this annoying problem? Many young men have not learned to recognize their premonitory sensations (the feeling of no return, just before orgasm. ) In order to slow down, it is vital that you learn to recognize these sensations. Doing so, is the first step to slowing down.How is this done? While masturbating, practice the following: Masturbate until you are about to have an orgasm (not after it’s started). Then, stop until your sensations settle down. In this way, you will train yourself to recognize the warning signs of orgasm and to stop before it’s too late. Keep repeating this cycle and gradually, increase the number of Start-Stop cycles. The more Start-Stop cycles you achieve, the longer you will be able to hold off during intercourse.Another way to hold your horses is what I call the ‘Squeeze Technique. ‘Once again, masturbate until you feel the Premonitory Sensations, then stop and squeeze your penis with your thumb on top and the other fingers on the bottom. Squeeze just behind the coronal ridge (the part of the penis that bulges out. ) Keep squeezing until you have gained control. Then, once again, practice the Start- Stop Technique, squeezing each time you feel the Premonitory Sensations beginning to rear their head.After you’ve gotten these techniques down, practice them with your girlfriend. This is the most fun learning curve you’ll ever know. What I have suggested should put this problem to bed. If you still have problems or questions contact me again.
