I am watching porn movies & masturbating from 3+ years continuously. I stop doing it very rarely. I got married last year June, till now I didn t satisfy my wife with my pennis. I am unable to insert it properly, it is not being stiff/hard whenever I try to insert. Before insertion, my pennis is very well hard. The moment I try to insert, then it is not getting stiff/hard/strong & not able to insert it. Please help me, I am very much worried about it from last few months. Is it because of my masturbation from last years continuously or something stress or should I take good foods or any health reasons ( I got very minor surgery near to brain because of some infection) or anything else? Please let me know. I m waiting for reply...
