Sustain your erections for longer with the Arab Strap which comes with a 35mm rubber cock ring. Slip the cock ring along the erect shaft of the penis and adjust the metal buckle fastening leather strap (that goes underneath the balls) to the appropriate level of tightness. A firmer, more satisfying erection will follow. The Arab Strap can also be used on a flaccid penis for the purposes of cock and ball torture where it is used as a chastity device to prevent intercourse.
