Public sex of any kind is illegal in many parts of the world, and police undercover operations continue to be used in order to enforce such laws.[8] Adverse personal consequences to participants in glory hole activity have included police surveillance, public humiliation in the press, often with marital and employment consequences, and imprisonment following a criminal conviction. Gay bashing, mugging, and bodily injury are further potential risks. For reasons of personal safety, as well as etiquette, men typically wait for a signal from the receptive partner to come through the hole before inserting any part of their genitals through a glory hole.
