Hai, I practice masturbation since 18. Now 25. I didn't have any sex either. Had a smoking habit 4 per day. For last 4 months my penis fails to erect.. got curved towards left.. semen is diluted... facing all sexual trouble.... now I cut masturbation, even smoking at considerable level. Anybody help me to sort out this problem. I need to have happy sex life...... out of ignorance I had to commit such a mistake.. .. is the problem is temporary or permenant.... can I involve in sex always happily and healthily or not.... please show me good ways....... my penis failed to erect
