Why does it take a long time to orgasm during sex?

Patient's question:

Having sex for a long time without being able to ejaculate recently

Doctor's answer:

Analysis of the condition: Anejaculation, also known as impaired ejaculation, is a condition where a person experiences normal sexual arousal during intercourse, with a hard erection of the penis and prolonged sexual activity, but without reaching sexual climax or emitting semen.
Guidance on treatment: The treatment for anejaculation mainly includes the following aspects:
1. Causal treatment, which involves removing the underlying cause.
2. Electric massage device treatment.
3. Appropriately adjusting the interval between sexual activities.
4. Medication treatment, under the guidance of a doctor, taking methylphenidate orally 30 minutes before sexual activity to stimulate ejaculation.
5. Assisted reproductive technology treatment.
