That's cock and ball torture in chastity terms. Chastity devices that have a CBT effect appeal to those looking for genital pain as part of play or a little assistance in staying mentally chaste. Devices like the Internal Spike Fence Cage would be implausible to wear for days on end, but are perfect for adding a level of pain to chastity play. As the penis becomes erect it is pushed up against the tiny spikes which line the inside of the cage and can help subside erection, but generally cause a pleasurably painful experience.
Long-term chastity users can turn to a CBT element to assist them in further controlling their sexual urges. The CB-3000 and CB Curve Male Chastity Kit can both be fitted with devices called Points of Intrigue (or Curve Points of Intrigue). These slide into the space between the scrotal ring and the chastity device and go unnoticed until the wearer begins to become aroused. The swelling in the penis causes it to push up against these points, which feels a little bit like Dracula sinking his fangs into your sausage. Not very pleasant, but a very effective way to quell your arousal.
