The invention concerns a stimulation device for a male penis, with a pressurefield generationdevice (1) for generating a pneumatic alternating pressure field, and anapplicator (11) forapplying the alternating pressure field to a portion of a penis that is to bestimulated. Theapplicator (11) has a pressure chamber (2), which can receive an alternatingpressure fieldgenerated by the pressure field generation device (1). The pressure chamber(2) has anopening (3) in a contact region (31) of the applicator (11), so that thealternating pressurefield can be applied directly to a portion of the penis that is to bestimulated via the opening(3). A sealing device (32) is arranged on the applicator (11), which isconfigured to seal thepressure chamber (2) against the environment when the applicator (11) isapplied to thepenis.
