Will blocking the horse's eye during ejaculation cause vas deferens blockage?

Patient's question:

No

Doctor's answer:

Hello, I don't quite understand what you mean? What is a horse's eye? The urethral opening? Suggestions: If you forcibly interrupt ejaculation, this can be harmful to the reproductive and urinary systems, easily causing conditions such as prostatitis, seminal vesiculitis, impotence, and more. Therefore, this practice is harmful.
