za RomanticMind0 :The first few times you do sounding it will hurt. It takes time for the urethra to become desensitized to something foreign being rubbed up and down it. Once you have been doing it for a while, it stops hurting (although there can still sometimes be a little discomfort). The trick is to start with small diameter rod, use lots of lube and go slowly. Start with inserting only a small way, maybe 1 inch and do that for a few days then go deeper, maybe 2 inches and do that for a while and slowly get used to it. I have been doing it for a long time. If you want to discuss it more just PM me.
za NakedKiwi :I've just finaly done 13 mm an hour ago. It was great to jump on a new level of beeing stretched. My cock is still not used to the new rod, but loves it. Now we'll have to practise much before 14 mm.
