The purpose of the cockring is to restrict the blood flow, from the penis after it has become erect,this not only maintains the penile erection(you stay harder for longer) it alls increases the sensitivity of the whole penis thus creating heightened pleasure and a more intense orgasm and explosive ejaculation............There Grrrrrrrrrrrrrrrrrrrrrrrreat you should try one...........................BUT WAIT A MINUTE............ wheres the rub,like every thing of pleasure in life there is a sting in the tail,if too tight and kept on for to long thay can cause circulatory and blood supplie problems in the penis and surrounding area,and there have been recorded cases of some guys getting inguinal hernias (not a pleasant condition in many cases needing corrective surgery)from too regular use of said ..........COCKRING........its all trial and error....GOOD LUCK..:wink:
