Can you continue having sex after ejaculation?

After ejaculation, sexual intercourse generally cannot continue, as the penis enters a flaccid phase post-ejaculation. Further intercourse during this period is not advisable because the penis cannot achieve a normal erection or sustain satisfactory sexual activity. Typically, the penis can regain its erect state within 20 minutes after ejaculation, making additional intercourse possible at that point. However, frequent sexual activity should be avoided, as it may negatively impact health and potentially lead to kidney deficiency (renal asthenia).
