Your clinical history does point strongly toward a diagnosis of Lifelong Premature Ejaculation (LPE). LPE is characterized by an intravaginal ejaculation latency time (IELT) of less than one minute from the very first sexual encounter, an inability to delay ejaculation, and secondary psychological distress. The fact that your
testosterone level 488.51ng/dL is perfectly normal and you have no erectile dysfunction confirms this is an isolated ejaculatory reflex issue rather than a hormonal or structural problem.
Your description of tolerance during indirect stimulation (through clothing) compared to direct skin contact highlights a pronounced hypersensitivity of the penile glans. The fact that the urge returns immediately after pausing indicates a low neurological threshold for the ejaculatory reflex, which is highly common and manageable.
Next Steps
Consult a Urologist or Sexologist: A specialist can confirm the diagnosis, address performance anxiety related to your upcoming marriage, and tailor a multimodal treatment plan.
Combine Behavioral Techniques: Start practicing behavioral therapy, specifically the "squeeze technique" or the "stop-start method" during masturbation. This trains the central nervous system to recognize and tolerate the "point of no return" over time.
Discuss Pharmacotherapy Options: Since you are getting married in 3–4 months, standard first-line medical treatments can be highly effective. Ask your doctor about on-demand Dapoxetine (a fast-acting SSRI taken 1–3 hours before intercourse) or daily low-dose SSRIs, which safely delay the ejaculatory pathway by increasing serotonin levels in the brain.
Consider Topical Anesthetics: Discuss using over-the-counter Lidocaine or Prilocaine sprays/creams. Applied 10–15 minutes before intercourse, they temporarily desensitize the glans to counteract direct skin contact hypersensitivity.
Health Tips
When using topical anesthetic creams or sprays, always wash the product off completely or use a condom before intercourse. If left on the penis, the residual cream can transfer to your partner and numb the vaginal walls, diminishing pleasure for both of you.
Alleviate the Pressure: Performance anxiety drastically accelerates ejaculation. Understand that first-time intercourse in a marriage is rarely perfect; focusing on mutual intimacy rather than an exact time limit will naturally help relax your nervous system.
