Hello dear, First of all remove all myths & misconceptions from your mind about masturbation. In fact, Masturbation is completely normal & doesn t have any bad effect to the body and mind unless you get addicted to it. 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. Have 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. If you still experience any difficulty, investigations like complete blood count, thyroid profile, estimation of blood sugar level will be helpful to rule out any chronic infection, hormonal and metabolic causes. Wishing a healthy life. Take care.
