B,
That sound looks huge in the pic. How long/thick is it? What kind of lube do you use?
What do you like about the J sound as opposed to a straight or curved one?
Well...It took some time and stretching before I could slid this bad boy in in my dick. As for it's size, most sounds are measured in French or FF, and this one is 34 as I stated . In standard sizing, it is 3/8 thick, and from the tip along the curve to the deepest I can take is 12". The end is flat and to wide for my slit to take it.
The difference between the J sound and a Van Buren lies in the curve length. The typical Buren from tip, along the curve to when it straightens out is 3". The J sound from tip along the curve to when it straightens out is 4 3/4 ". I have not been able to find any place that still carries the J sounds
To use it correctly for deepest insertion. I insert the tip with the curve facing upwards. Slowly allowing it to make it's way in, you can feel it when it hit the opening in the prostrate , I then slowly lower the sound downwards. There will be a slight "pop" as it enters , then it passes into the bladder.....

For me it just feels really good. I use ID Lube Glide original formula
Like some of us have stated this is not for everyone. If you get brave start out small and see how you like it yourself.
Word of caution: NEVER push the sound in and stop if there is pain.
Have fun and play safe.
