I am 20 years old male. I occasionally drink and smoke since past 3 years. I used to have an active sex life. Also I used to masturbate daily. Since few weeks I cannot get hard erections as I used to. So I tried watching porn to check whether I can get erections and got partially hard. Now I am worried. I quitted smoking and liquor a month back. I do workout daily and tend to lift heavy weights. I also have protein supplement intake (muscletech nitrotech whey+lean muscle with 3g creatine and etc). How can I get hard erections like earlier and regain my libido. If possible please suggest me natural methods. Thank you.
