Hello dear, Regarding the problem of Erectile dysfunction, it is due to decreased blood supply to the penis. Though medications like Cialis & Viagra increase blood flow to penis & maintains erection, it can be improved by having a diet rich in fruits, vegetables, fish, nuts & honey. 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. Avoid stress...practice meditation..this helps in improving concentration & builds up the confidence level. Avoid smoking & alcohol. Despite these measures, if you experience difficulty, it will be better to rule out other causes like high blood pressure, blood sugar and other local causes that impair blood flow to the genital organ. 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. Wishing you a Healthy Life. Take care.
