I'm new to sounding but really love it. I've got a beaded one like in this video although not as long but love the resistance it gives and the pop as the bread are pushed in and pulled out.
The sounding rod has to be smooth with no rough edges. Insert the narrow end first so it can go through the tightness. Use more lubes. Use steel rods, thin ones of 6 to 10mm thickness as beginner. The hole will stretch when u do it more often n try bigger size slowly.
Excelente tu video tengo esa misma sonda y se siente muy bien cuando la tienes hasta el fondo no se diga correrte con ella dentro y si alguien mas es quien la mete y saca mientras estas atado de pies y manos ufff
I wanna try sounding and I got a toy but when I tried it my penis hole was tight when I was pushing the toy down any ideas on how to get past the tightness
