But men should know that while yes, PE can be incredibly frustrating, it's also incredibly common. “Premature ejaculation is a problem that affects almost every man at some point in his life,” says Thomas J. Walsh, M.D., a urologist at the University of Washington. Many men consider lasting longer during intercourse as a sign of their sexual prowess and why not, after all it really enhances the sexual pleasure of their partner. A normal male orgasm takes around seconds. Extending the arousal phase can double that and increase the orgasmic intensity a LOT. Many men who practice tantric sex also experience pre-shocks and/or post-shocks.
