Hello dear... Welcome to HCM Regarding the problem of premature ejaculation & nocturnal emission, it s mostly related to anxiety. So...don t worry about all this & stay relaxed Performance can be improved by having a diet rich in fruits, vegetables, fish, nuts & honey. Avoid stress...practice meditation..this helps in improving concentration & builds up the confidence level. Avoid smoking & alcohol. You can also do oil massage of the penis...it increases blood flow & maintains the erection. Also...connections between erectile dysfunction & excess use of porn has been reported in many studies. For those affected, recovery takes place by 6-12 weeks & mainly involves avoiding the causative factor, that is watching porn. 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.
