Why the purple color

[dwm4re]

Ok guys I have a question. I pump maybe 3 or 4 times a week. Goal is girth and length if possible, but I just really enjoy the feel. This pic is of only 20 min at a 5 pressure in my 2 inch tube. I get this purple color on my shaft and on the ring of my head. The pressure doesn't seem to be too much and the amount of time , from what you guys have suggested, doesn't seem too long either. Comments?

It's a constricted blood supply from the tube base. Take off the tube, massage then go in again. Also consider a cushion base that allows a wider spread of the pressure from the base over a larger area, like the Oxballs Juicy.
