I had been fooling around with sounding for a while, mostly with much shorter(and smaller) sounds. Then I decided to "jump in" to the big game. I looked at several types and decided on the Rosebud set. Nothing prepared me for the actual sizes an LENGTHS. I started small(6)mm. It would go so far then I hit a wall. I gradually went up in size. As I went up in size, the pleasure factor increased exponentially but I still "hit the wall at the base of my prostate. Using a 8 mm sound, I bent the sound approximately 30 degrees, lubed up again and tried once more. As the sound went in there was a slight resistance and then the most wonderful hot feeling as the sound touched the base of my prostate! I just left it there enjoying the feeling. Already, it was 10 times the sensation of the "finger" process. Slowly I gave a little push. As the bulb entered my prostate, I thought that the pleasure would make me pass out. I went right through the urethra. As the bulb passed through pushing on the walls of my prostate, the pleasure was incalculable. I had to lean against the bathroom wall in front of the toilet because the pleasure was so intense. I have since graduated to 10mm. The pleasure is just so much more intense. Yesterday, I used my trusty modified 10mm and I started "massaging" my prostate from the base to the bladder. I just kept sliding it in and out. I could feel it building and within moments I had a truly explosive orgasm. These sounds are truly wonderful! They are the proper sizes and lengths. Because of the thin rod, they can be bent very easily to accommodate your particular penile requirements. TAKE IT EASY. Use plenty of lube and go slow! I am going for 11mm now. my problem seems to be "the meatus" is putting up resistance. They ar very easy to clean and sterilize. With these rosebuds, you really don't need anything else to give yourself earth shattering mind blowing pleasure. Very highly recommended!!!
