The exact reason why some men ejaculate too quickly during sexual action is not fully known. This is called primary premature ejaculation (PPE). It is thought to be caused by a mix of genetic, biological, and social factors. Anxiety, worry, performance pressure, or early sexual events are all psychological factors that may play a role.

Biological causes can include changes in the amounts of neurotransmitters, hormonal issues, or a penile that is more sensitive than usual. People may also be more likely to get PPE because of their genes. Problems in relationships or cultural factors may also play a role. Behavior modification, coaching, and sometimes drugs are all common parts of treatment. People who are having PPE should talk to a medical worker to find out what is causing their condition and what the best treatment plan is for them.
