Herbs to decrease male libido?

Is there anything I can take to temporarily suppress my libido? I don't have a g/f and the urge to have sex is sometimes uncontrollable. Of course I release it the obvious way but even that takes up too much of my time and it doesn't help that much. I have actually noticed some success with tofu but I don't want to risk it having a permanent effect.

1. PUT ERECT PENIS INTO HOLE OF BOX.

2. FILL BOX WITH TARANTULAS AND SCORPIONS.
