Hey Julian, just a quick question about using the Phallosan. I have been using it for a month now and find it great but was wondering two things: Can and should you clean the protector cap? If so, what can you clean it with? Also, in relation to the traction level you are using, should you gradually increase the pull of it throughout your use of it? I have been using it for a month in the green but have recently tightened it to go to yellow because I think I got used to it. Should I gradually increase it over the next few months as my penis gets stronger with it?
