The Tenga Men's Training Cup Finish Training Lv.4 is the fourth part of a course designed by Japan's leading adult brand to help train you to finish better during vaginal intercourse. Jerking off too much can result in your penis becoming overly used to the snug feel of your hand to reach climax, meaning you struggle to finish during sex with a partner. If this problem of delayed ejaculation affects you, try the Men's Training Cup Finish Training cups, beginning with either the second or first in the series, and then working your way up. The one-use cups feature stimulating inner sleeves that decrease in intensity and tightness as you progress, training you to enjoy the feel of a hole that is similar to a woman's vagina. This is the medium soft type, starting with a narrow corkscrew and then widening further inside.
