PROBLEM TO BE SOLVED: To provide an ejaculation promotion tool cylindrical member and an ejaculation promotion tool which reduce an amount of a lotion used as a lubricant as much as possible, and achieve an excellent use feeling.SOLUTION: An ejaculation promotion tool cylindrical member 5 used for an ejaculation promotion tool 1 is configured to include a water absorption resin in an elastic polymer as a component material so that a contact of an insertion part 52 of the cylindrical member 5 with water and the like can make a surface of the insertion part 52 slidable, which can also minimize an amount of a lotion usage owing to the slidability appropriate enough to substitute a part of a lotion poured into the insertion part 52. In addition, sliding acquired by bringing water into contact, exuding from the insertion part 52 of the cylindrical member 5, causes integration feeling with sliding of the insertion part 52 and a penis to be enhanced during use time, and discomfort due to excessive use of the lotion in a conventional art not to occur, a proper level of insertion feeling can be acquired, so that the ejaculation promotion tool 1 and the ejaculation promotion tool cylindrical member 5 can provide a good use feeling.SELECTED DRAWING: Figure 8 |
