A man has been rushed to hospital with huge blood loss after a massive bit his penis while he was on the toilet.

Atthaporn Boonmakchuay, 38, was sitting down on his toilet at his home in Thailand when he suddenly felt a sharp bite to the tip of his penis.

When realised what was going on, the snake wouldn’t let go.

He yelled for his wife to come and help as he and the snake began fighting around the bathroom.

The vigorous fight with the reptile splattered blood all around the bathroom.

But just before he passed out from huge loss of blood, he grasped the snake by its head and managed to use a rope to tie its head to the bathroom door.

The ingenious move helped to detach the reptile from his penis.

The 38-year-old admitted later that he thought that his penis might be ripped off.

It is believed that the snake swam up a pipe into the toilet.

Incredible footage shows how the emergency services managed to take the snake out of the plumbing.
