Sir: I am suffering form premature ejaculation. My erection is ok. It erects within 2 to 4 seconds if I am thinking about some sexual thing. But if I masturbate or do sex, I ejaculate within 3 to 4 seconds. Please help me out. Tell me some exercises and about what I should eat especially in fruits and food that help me to cure my problem. My age is 25. I want to avoid medicine and I have not taken any checkup for this. Hope you can help me. Thank you.
