personally IMO I have seen great results both ways, and I went to chettawut, the benefit I believe would be better depth, and perhaps being able to save more nerves, and scrotal skin tend to be very elasticey. Again Jmo oh and in 2 months I was able to go to the largest dilator, have had very little pain, and almost no blood what-so-ever, and my healing is very fast, but I do not believe all of this to be normal, I think my faster than norm healing is because of my anemia, IDK I'm not a dr so... and Also I started with a candle for m dilation, which at that time had thought that it would mean extended dilation time to get to he larger size... so I have been pleasantly suprised 🙂
