everytime i masterbate i can only get up to a certian point like where my whole body shakes and then thats it i have to stop because its so intense. is there anything i can do to over come this.. i havent had an actual orgasm before although very close
Like, it's too sensitive? If that's the case, it should get less and less sensitive the more you masturbate. For now, just stop when you can't go on any further, take a small break, and go at it again. It should get less intense over time.
You could just force yourself to do it. An example of this is me eating a large quantity of mayonaise. Try some pychological games like telling yourself to not eat unless you go through with it. To be more effective write it on paper and post it on your door so that you have to read it. If that doesnt work have someone else do it while you are strapped into a gyno-chair.
