Bethany: Hi, Callum, I have a question.
Callum: What is it? Can't you just ask google?
Bethany: You're better, hahahah.
Callum: Hahah, thanks.
Bethany: So, what is it "sounding"
Callum: it's also called "cockstuffing"
Bethany: sounds weird.
Callum: it's a BDSM/kink practice.
Bethany: And you shove things into your penis?
Callum: yes, that's what they do!
Bethany: Anything?
Callum: of course not, here is some wikipedia: "Urethral play can involve the introduction of either soft or rigid items into the meatus of the penis (as well as farther in). Objects such as sounds are usually only inserted about halfway into the glans and can usually be easily retrieved."
Bethany: Isn't it dangerous?
Callum: Theoretically it is, if you don't do it carefully. But people who practice it claim it's not, and allegedly it's quite pleasant and stimulating.
Bethany: Oh, I was wondering why would anybody do it?
Callum: But you can have the same question for many things we do in life, right? Why do people go bungee jumping?
Bethany: Right.
Callum: But sounding is supposed to stimulate, it's pleasant as the people claim, also the idea of penetration is stimulating for some of them.
Bethany: Are there special objects for it?
Callum: Sure, you can even buy a sounding-kit, you'll find everything on the internet. 
Bethany: The whole new world for me!
Callum: Haha, but good to know:)
Bethany: oh, sure!
Sounding is a BDSM/kink practice involving shoving things into a penis. It can be dangerous if performed carelessly. Sounding kits are available for sal on the internet.
