To give a hickey, start with kissing and ensure you have your partner's consent. Make an "O" shape with your lips, press firmly against your partner's skin (commonly the neck or other intimate areas), and create suction by sucking the skin for about 20-30 seconds. The suction breaks tiny blood vessels under the skin, forming the reddish mark known as a hickey. It's important to be gentle to avoid pain or injury, and communicate with your partner throughout. Avoid biting or excessive pressure. Hickeys usually last from 2 days to 2 weeks depending on intensity and individual skin sensitivity. Also, avoid sensitive areas like near major veins or arteries for safety. This method combines passionate intention with care to make the experience enjoyable and safe for both partners.
