Reassure you young submissive, it is not your penis which is likely to be long is hard with this cage of chastity out of metal!
This metal chastity cage is relatively long, its total length reaches almost 10 cm. What could give you the false impression of being able to get hard, and that's precisely the sadism of this penis cage!
Depending on the size of your sex at rest, you can hope to reach a "half-soft" but in no case a total erection. It is unhealthy and strictly forbidden by the dominant Master (or Mistress), you wouldn't want to disobey him?
