I'm curious if the phallosan will make you thicker just like the bathmate or is the phallosan just a lengthening device? If the Phallosan does make you thicker is the bathmate still needed?
Phallosan is mostly for length, you might gain very, very little girth from it, but I wouldn't count on it, especially if you don't do any girth exercises.
The head is only expandable to the maximum size it is when it is filled to the maximum with blood. The only exercise that will allow you to utilize the full potential of your head size is becoming proficient at Kegels and get to the point that you can flex and hold a Kegel for some time. Eventually, with continuous training, your endurance will skyrocket to the point of using that flared head in sex.
