Is it normal to ejaculate before entering?

Patient's question:

Patient Age: 23
Detailed Medical Condition and Purpose of Consultation: I have never had sexual experience before. A while ago, when I was having sex with my girlfriend, I became very nervous. Before my penis even entered her vagina, I ejaculated. This has happened several times. Is this normal?

Doctor's answer:

Hello: With a history of sexual diseases, premature ejaculation is considered, and symptomatic treatment can be provided.
Treatment for premature ejaculation focuses on prevention. First, it is essential to strengthen sexual education and understand the physiological differences between female and male sexual climax, which typically occurs later in women. If a couple occasionally experiences premature ejaculation, they should not blame the male partner. For more significant cases of premature ejaculation, the couple may temporarily separate for a period. This can help break established pathological conditioned reflexes and allow sexual function to be adjusted and the reflex for ejaculation to be rebuilt. Close cooperation between both partners can also extend sexual intercourse time, ensuring mutual sexual satisfaction. During intercourse, avoid excessive excitement. When nearing ejaculation, stop the in-and-out motion of the penis in the vagina and divert attention from the sexual organs to non-sexual areas. Those who experience premature ejaculation due to excessive indulgence or prolonged masturbation may gradually reduce the condition by practicing moderation and abstaining from masturbation. For those with premature ejaculation caused by organic lesions, treatment targeting the underlying cause should be administered.
　　(1) Western Medicine Treatment:
　　A. Oral Medications: To reduce excitability, low-dose anti-anxiety or sedative drugs can be prescribed. Choose one of the following:
　　Tr 0.1–0.3 grams, three times daily.
　　Luminal 0.03 grams, three times daily.
　　Oryzanol 10 milligrams, three times daily.
　　Probenecid 30 milligrams plus Stilnoct 20 milligrams, once nightly.
　　Take 25 milligrams of thioridazine one hour before intercourse to inhibit ejaculation.
　　B. Topical Medications: Wash the glans penis 0.5–1 hour before intercourse and apply a small amount of anesthetic cream, such as 1% Dyclonine ointment, or 1% procaine.
