The present invention provides a self-suction type vacuum suction device for males. The suction device is particularly designed thereon with a locking assembly which comprises membranes and is matched up with a regulating member to regulate with each other, so as to regulate air to enter an upper partition part, a lower partition part, and a cup body, thereby achieving a locking function via the membranes. When a male genitalia enters a soft rubber sleeve in the cup body, a feeling of suction force or pushing force is generated immediately, wherein the strength of the suction force or the pushing force can be arbitrarily regulated by the regulating member. Therefore, the speed of pumping can be controlled by the user and the present invention is very safe and convenient to use.
