I have problem of early cumm. And erection also hold for small interval of time. Initially before sex it erect and in foreplay only as soon as my girlfriend touched my penis I ejaculate and erection become weak suddenly and I loses the ability for sex. I am very dissatisfied and my sex life is become very worse. I wanted to eat viagra or tadafil or manforce tablet to maintain erection and long last. But problem is I have never tried. Can I eat tablet before consultation the doctor. As I have consulted doctor regarding this problem, he gate me pari 10 mg and virilez. I ate it for many time which was inefficientive.
