I got the hydroextreme 7 and have been using it for about 10 sessions so far doing the 3 min jelq 5min pump x 3 sets. The pull at my base feels amazing and I feel like I could go more pressure with the pump tho my head starts to get this odd prickle tingle sensation and when I take the pump off its a dark red purple. It this to much pressure? Do I have to wait for the head to adapt first? I also bought the length master so will be adding that into the routine with it if anyone has any suggestions there. Also heard using a cock ring is good too. Cam anyone speak for the ball stretcher product also? Figured I might as well strengthen the whole area. Cheers
