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.
