Always start with a thin rod and not sharp on the end always lube otherwise after sounding slot it will hurt when you pee. And make sure its clean or you coukd get an infection. Its a lovely experience
Yeh wow, you shot out heaps of cum too! It really surprises me how deep it goes! Does it hurt at first and is it safe? I’d like to give it a go one day as I’m sure it’s pleasurable 😋
Sounding with the biggest Hegar rod that stops cum escaping is one of the finest joys one can have. For me, it is mm for the moment. Use some gentle force, but never hurt yourself while stretching your peehole. Friendly regards, Hans.
