Thanks for your query.You had a problem of Premature Ejaculation
for which you were taking drugs.and now yo have a problem of getting hard erection. Assuming that you had normal erection earlier your erectile dysfunction
that you have now is called a Secondary ED and most of the time it is Psychological related.It can be cured by moderate exercise,diet and meditation
.This will settle down over a period of time.You can discuss the issue with your wife and seek her help Spend more time in fore play during sex this will help you in getting hard erection.You can take Tab Sildenafil
before sex after consulting your family Physician.
