Bumpy Dick

So, I'm getting little dry bumps around the head of my penis. I think they are from wearing the extender too long, as they appear where the noose holds my penis in place.

Am I leaving it on too long?
Is it too tight?
Have you seen this before?

I will say, I have been wearing it about an hour or more at a time and my head is pretty purple by the end. I let fresh blood in for 2-3 mins then restrap.

Routine: I also slept in fowfers last night, switching sides each time I rolled over.
