Hello dear... Regarding the problem of premature ejaculation, it is mostly related to the anxiety of whether you would be able to perform well or not. So...don t worry about all this & stay relaxed. Avoid stress...practice meditation. 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 increase the size of penis or 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.
