Should My Glans Be Purple During Jelq?

After 20ish jelqs my glans become fully purple, is that bad? Good? Normal?

I could only find info about bruising and purple botches.

It’s fairly normal, but it should also go away quickly, too.

Thank you. It goes away as soon as I stop jelqing.

Do you know of a post on what should I expect and feel during a session? I only found descriptions of the motions.
