Bathmate Question

So like everybody else my testicles were getting sucked into the bathmate so I used a hair tie to keep them out. Now my sack is pretty long and hangs low…I’ve been putting the hair tie all the way at the bottom and I get a great seal but I noticed the top half of my penis is darker than the base as if it’s sucking in skin and not expanding the penis towards the base. So my question is, is that ok to keep doing or should I put the tie as high as I could?

The ball sucking effect had me concerned about the use of this device. But by relaxing in very warm water in the tub, the testes moved lower and then I grab them with the left hand to hold them down out of the way while applying the Bathmate up as far as it will go against the base of penis. Then a couple pumps with the right hand to stabilize the position usually keeps things in proper place. Not pumping too quickly helps the starting process. Try this first. Otherwise, yes, try with the tie up a bit higher. I wouldn’t be concerned about discoloration unless it becomes worse going forward over the next few days. If so report back.
