Hello dear.. Regarding the problem of premature ejaculation, it s mostly related to anxiety or drug abuse. So...it will be better to de-addict yourself from intake of phensidyl syrup or other forms of drug abuse. Avoid stress...practice meditation..this helps in improving concentration & builds up the confidence level. Medications like Viagra increase blood flow to penis & maintains erection However...performance can be improved by having a diet rich in fruits, vegetables, fish, nuts & honey. Avoid smoking & alcohol. You can also do oil massage of the penis...it increases blood flow & maintains the erection. One more thing...avoid consuming any over the counter medication which claim to improve performance...it may be harmful. Best thing is to eat a healthy diet, exercise regularly, avoid stress, get good sleep, think positive and stay happy. Wishing you a Healthy Life. Take care.
