Los Angeles - Charlie Hunnam creates a "hand Jacuzzi" by cupping his butt with his palms in the shower.
The Sons of Anarchy actor enjoys experimenting with his naked body while having his daily wash and joked one of his favourite water-based experiences is simulating a hot tub's bubbling water effect with his derriere when he needs to let one rip.
When asked about his shower activities, he said: "There's the hand Jacuzzi, which we've all tried right?
"When you're in the shower and the water's running down your back and you need to break wind. If you cup your bottom and let it fill with water, you can create a little hand Jacuzzi."
When he is not getting inventive in the shower, the 34-year-old star - who plays Jax Teller in Sons of Anarchy - can be found out and about getting plenty of female attention and recalled one instance when an over-excited fan shouted that she wanted to sexually assault him.
Speaking on chat show Conan, he added: "I was riding recently, minding my own business, it was early in the morning, I think I was actually going to work.
"I stopped at a red light and somebody said, 'Jax! I wanna fucking rape you!'
"So I said, 'Can I have my breakfast first? ... I just said, 'Thank you, have a nice day.'"
