An endurance condom - also named a climax delay condom - has a small amount of benzocaine gel, which is a local anaesthetic, inside the tip. With the warmth of your glans, this gel will melt and penetrate the erogenous zone to delay your ejaculation. Besides, its special narrow shape gives a slight pressure on your erectile nerve while slowing down your blood flow. All these actions will contribute to a long lasting relation for everybody’s pleasure.
