The TENGA CUP features the Smooth Pad insertion mechanism! This mechanism not only offers extra adherence, air-tightness and less lubricant leakage, but will automatically apply lubricant to your shaft as you insert!
Use it once and throw away. No muss no fuss and a really good time! Masturbation sleeves are also a great way to learn to have more reliable erections and ejaculatory control.
Practice, practice, practice!
