Hi Typex, If you want ED just carry on what you doing, then you will have no erections, your p***s will be dead.
Time to clean up your act forget porn and masutbating to it or you will end up with porn enduced ED, porn has a part in life for sexual arousal by couples, best, and there it should stop.
Best thing you can do is clear away all your porn sites, if you have any downloads get rid of the, and if you have put anything on disc throw them away, this is all best advice.
Good Luck
when you have erection at a wrong time, do abdominal breathing. Google for abdominal breathing. This will calm you. You can start abdominal breathing the moment you feel that you are going to get aroused. Another method is circulating your sexual urge around microcosmic orbit.(Google it). Supressing sexual urge is difficult. you can convert this energy to mental energy. Practice the above methods. If you learn and practice this method, your sexual energy will help you to build up your will power and change you completely.Masturbating when you get enough time,and when can you enjoy, is ok. Do not build tension if you have to masturbate. Porno is worst. Decide to stop seeing porno. It will ruin your life. Sex is a subject of reverence. If you are interested in self improvement and progress, you may learn kundalini yoga. there are many web sites on it. learn and practice.
Hi and welcome. As a man with similar experience, think its ok what your doing but does build up pressure and its quite uncomfortable. Since your living in a shared household where people pop in and out, try to find a spot where you can relax and enjoy yourself. Some day you will have your own apt and can feel safe that no one will disturbe you.
