Train and Practice your kegel muscle (pelvic floor muscle).
Pelvic floor exercises can be effective in treating premature ejaculation in men who have had lifelong problems.
A team led by Dr Antonio Pastore (Sapienza University of Rome), group took 40 men (aged 19-46) who were suffering from PE and trained them to exercise their pelvic floor muscles over a 12 week period. They also measured their time-to-orgasm over this period. Previously, the men had tried a variety of therapies, without any significant improvement. At the start of the trial the average ejaculation time was 31.7 seconds, but by the end of the 12-weeks of pelvic floor exercises this had risen to 146.2 seconds 2– a more than 4-fold increase.
