A lot of people assume it is when a man ejaculates in under a minute, but it is actually when a man cannot keep himself from ejaculating before he wants to. It is therefore a complex in the brain, and not the penis.
Premature ejaculation is also different to erectile dysfunction (ED), when a man's penis loses its hardness. But often, PE ties into ED when the man has ejaculated, he loses his erection and doesn't continue the sexual experience.
This course is not just going to help you manage your PE, but also learn that there is much more to sexuality than just penetration and orgasm. Sex is really about a journey, a journey to connection, satisfaction and pleasure.
