In my last visit I remember him only looking at it externally and asking me how I feel. Next visit is in June 1st. Until then I am to continue 3 dilations a day. He said 15 min each but I am doing longer because it takes longer to get to the most depth I can reach and I am also using silicone dilator which happens to be wider before using my plastic dilator which happens to be deeper so I do at least 15 min each to be sure and sometimes 30-45 min with the silicone until 10-15 min pass that I can't go any deeper.
Their average diameters are 3.5cm, the silicone one is wider at the base (about 4cm) compared to the plastic which has a more uniform diameter. Silicone depth 14cm, plastic 16.5cm. Right now can almost get entire silicone in, missing maybe a cm and am missing about 3cm from the plastic.
Is that supposed to be adequate for most penises or should I strive eventually for the largest 4.2cm average diamater silicone dialator with 15cm depth?
Also, the white stuff kind of looks like cheese, except white instead of yellow.

Is that common?
