i dont know about these local drugs
but i can give some psychological advice
there are three basic exercise to overcome this prob
1.start and stop
this is often referred to as the squeeze technique or the start-stop technique. The squeeze technique was developed by Masters and Johnson in the late 1950s. The partner manually stimulates the patient's penis until he is close to the point of orgasm and then squeezes the penis just below the glands for 3 or 4 seconds. The partner does this until the patient loses his urge to ejaculate. The goal is for the patient to become aware of his sensations that lead up to orgasm so that he can learn to control the timing of ejaculation. The couple then progress from the manual squeeze technique to stimulation of the penis during motionless intercourse in the female superior position and then finally to intercourse in the lateral position with both partners moving.In the stop-start method, the partner stimulates the penis manually until the man feels the sensations premonitory to ejaculation. He then instructs her to stop. Once the premonitory sensations have passed, he then instructs her to restart stimulation. Both of these methods require repeated practice and both of these methods are obviously going to be met initially with a lot of frustration, so it requires committed partners to work on these.
start and stop technique to increase the time until ejaculation. This requires a great deal of couple cooperation and communication, and may be difficult for some
2.The quiet vagina
The quiet vagina is a name given to a technique whereby the female partner stops moving during intercourse as soon as the partner approaches climax. Masturbating before having intercourse is most often something that is done by younger men. They come about this on their own. They discovered that if they have a masturbatory ejaculation that subsequent intercourse performed directly during the refractory period results in greater control. This is often a self-taught strategy for younger patients with PE. Unfortunately, it's probably not an option for older men who have longer refractory periods or for men who might be using short-acting phosphodiesterase inhibitors.
it might be a technique that would be reasonable to use for an individualwho is using a long-acting phosphodiesterase inhibitor. Short-acting phosphodiesterase inhibitors are Viagra (sildenafil) and LevitraCialis (vardenafil); the long-acting phosphodiesterase inhibitor is (tadalafil).
