The JBoa is created to give you a rock hard penis. The constriction of the base of your penis leads to restricting blood in your erect penis; which results in prolonging your erection. The constricting effect also results in a mind blowing, very powerful ejaculation because your sperm is squeezed out under pressure.
The JBoa is your ideal mate during intercourse as well as during masturbation. Wearing it for some time during the day - for instance during your daily shower - with a half erect penis makes your penis feel bigger and more sensitive throughout the day. While the JBoa constricts your penis and keeps the blood in it, you really need to follow the indication of your body and de-constrict or loosen the string when required. The JBoa is made from a comfortable feeling, high quality silicone in combination with a stainless steel cylinder. This amazing stylish One Size fits all Lasso comes in a shiny black aluminum tube which can be your companion everywhere you go.
