I have premature ejaculation, hw can i improve it by exercise n. natural medicine to improve my sex health?

No evidence: Premature or rapid ejaculation has not been shown to respond to exercise or "natural medicine." your best bet is to talk to a sex therapist or sexuality counselor about it. Some men also take antidepressants -- not because they're depressed but because the medications tend to delay orgasm.

2 possibilities: It is possible that pe is associated with insufficient amounts of the neurotransmitter serotonin. Many commonly used drugs for pe are ssris (selective serotonin reuptake inhibitors) 5-htp is sometimes used to increase serotonin levels. It is a lot cheaper than the drugs, and worth a shot before going the drug route. Also, you could try a desensitizing cream applied topically.
