The couple ended up in a hospital in Hanoi with scratches after the young man attached the bag to himself.

Vietnamese newspaper Tuoi Tre reported that he used a bag as he was too shy to buy condoms.

The paper said: “As the plastic bag was rough and lacked elasticity and lubrication, the young couple ended up scratching their genitals to the point of bleeding.

“The lovebirds underwent a thorough check-up and were prescribed with antibiotics and disinfectants for their injuries.”
