Learn control*As with all great sex, it starts in your head. Turn off all the negative messages involving worry and stress.
*Practice self pleasuring involving more than just stroking the penis to erection and ejaculation. Sex is about a whole body experience, not merely the genitals.
*When self-pleasuring, approach, but not arrive at the point of no return. At this point pay attention to how it feels, what body changes are taking place, the sensations, breathing, and the urge to release. Back off a bit, and stay aroused without ejaculating. At this time use the squeeze technique developed by Masters and Johnson. this calls for squeezing ghe penis at the base or the frenulum (sensitive spot on the underside of the penis) until the is some distance from the point of no return. Then return to more vigorous self-stimulation. Repeat this several times over several sessions. Approach your point of no return, then back off using the squeeze thechnique. For most men, it doesn't take long to develop good ejaculatory control while alone.
* Once you've practiced and feel you have good control during masturbation, then try it with your partner. Allow her to do the squeezing for you.
