The man was using a portable toilet on a Sydney building site, when a spider bit him on the penis.

Five months previously his penis was bitten by a redback spider on a portable toilet at the same building site.

Jordan (surname not disclosed) told the BBC: “I’m the most unlucky guy in the country at the moment.”

“I was sitting on the toilet doing my business and just felt the sting that I felt the first time.

“I was like ‘I can’t believe it’s happened again.”

His work mates were keen to make fun of him as he left for the hospital for a second time.

A redback spider bite causes severe pain, sweating and nausea.

If he carries on at this rate he’ll be changing into Spiderman.
