First off: What is Ringsting you ask?
Its a stinging sensation around and or in the ass-hole that can be caused by 3 main factors:
1). The sharp or hard shit: When pushing out a really hard or pointy shit it ever so slightly cuts the side of your ass-hole.
2). The spicy shit: This is the one which is most likely to happen too you. When you eat a lot of spicy or acid laced food such as harsh vindaloo or drink 2 litters of some of that motherfuckin pure as shit innocent OJ.
3). Cheep toilet paper: Wiping that ass with some of that cheep own-brand Tesco razor blade laced paper is going to leave your ass bloody as fuck.
If one of these has affected you then their is an easy solution to ease your pain... The Ice inserter, To create this all you have to do is stick your finger in ice-cold water and then ram the little guy up your bum.
While factors 1 and 2 are non-preventable, 3 certainly is. Buy nice soft toilet tissue and your ass will thank you.
