I was just wondering why does it take me so long to ejaculate?

See answer: Delayed ejaculation causes include: aging, some chronic health conditions (diabetes, neurologic, low T, hypothyroid); surgeries (prostate, abd/pelvic); medications (BP and pain meds, anti-depressants); substance abuse (alcohol, recreational); or mental health problems (depression, anxiety, stress). In many cases, delayed ejaculation is due to a combination of physical and psychological concerns.
