This is an amazing, inventive toy and it's made a huge difference to the sex lifes of more than one couple we've talked to! Simply slip the ring around your erect penis (it is made form Cyberskin trademarked rubber, which is soft and stretchy to accomodate every size) - it'll stop the blood from leaving the penis leaving you harder, more sensitive, and more strongly erect for longer. Then slip the multi-speed vibrating bullet into the ring and make love as normal - the vibrations against her clitoris will send her over the moon and it feels pretty good from your end too!
