Women are often disappointed in their male partners when after few thrusts the whole excitement ends.
Premature Ejaculation is arguably the most common sexual disorder in men <40yrs.It is unfortunately a reason for infidelity and marital breakups.
It can be lifelong or acquired.

The reasons for premature ejaculation include:
Anxiety
Attitude towards s*x
Female partners
Drugs.. antihypertensives... psychotropics
Organic problems
Inorganic problems
Severely delayed orgasm in female partner

The way out include
1 extensive pre-intimacy
2 the man should calm don't just dive
3 female should not condemn the lazy guy, just talk to him tell him he can do better
4 use condoms
5 some drugs are of help if the above are not adequate
It is your duty to make your partner enjoy it

Agreeably, premature ejaculation is extremely embarrassing and is anathema to the progress of most relationships. There are several other ways of approaching a solution also:
Kegel's exercise: these set of exercises target the pubococygeal muscles and strengthen then. Research has shown that strong pubococcygeal muscles reduce premature ejaculation and increase the depth of orgasm

Breathing techniques: controlled breathing is shown to have some connection with better health and reduced anxiety. Anxiety is one of the culprits of premature ejaculation and any means of reducing its effects is indispensable.

Desensitization sprays: these sprays contain lidocaine which is a mild topical analgesic. A few sprays 10 minutes before sex will reduce the sensitivity of the penis and prolong sex by several factors. Users claim to last more than twice their normal duration. Residues which haven't been absorped can't be wiped off before penetration assuming one is not using condom. These include stud 100 (which I found here in Nigeria http:///stud-100-ejaculation-delay-spray-1176695), shibari, premjact and several others
