This is my 3rd day of using the bathmate. I have the basic hydro, and went in flaccid. After like 7 or 8 pumps I was feeling some discomfort but nothing too bad so I just maintained that level for 5 minutes. When I pulled out of the bathmate though my penis was a little bit purple for a few seconds. Do you think this is normal or something to be concerned about? It went away quickly and I have no pain.
