Ejaculation promotion tool and ejaculation promotion device

摘要

By using the pressure of the air in the non-closed air chamber formed between the core member and the container as a pressure source for stimulating the penis and tightening force, the stimuli and tightening force can be varied due to appropriate pressure. An ejaculation promoting tool and an ejaculation promoting apparatus capable of obtaining the above are provided. A core main body (31) having an insertion port (33) and an insertion space (35), and a plurality of first ribs that protrude from the outer peripheral surface of the core main body at a required interval and extend in substantially the same direction. (40), and when the outer diameter of the core body expands, an air resistance member (50) that allows the passage of air along the flow path while providing resistance to the air flowing through the flow path F is provided.
