Pelvic Bone Pain

I recently purchased a penis pump with a gauge and curved edges. The pump works great, it builds pressure and stays pressurized with no problem at all. I am going to the recommended 5 hg and not leaving it on for more than 10 minutes at a time. The only problem is the pressure is causing the curved sides to dig into my flesh, pushing the tube against my pelvic bone. This is not necessarily painful, but it is quite uncomfortable. Has any body else encountered this problem?

You might try pumping at less than 5 in Hg vacuum.

I use a velseal cylinder which eliminates this problem as it has a padded/silicone sleeve at the base. Very comfortable!
