Question about hanging and Glans darkness (Wench)

OK. So I’ve done a fair bit of research, built me a Captain’s Wench,
and I’m almost at 2 weeks of hanging (5 days on 2 off). So far everything is great and I’ve got no abnormal soreness going on. However, after 15 minutes of hanging, my glans gets kinda dark.

The discoloration goes away right after I release the Cable Clamp while I’m resting between sets (I’m doing 3x 15min. sets with about 5-10 min breaks in between at 5 lbs). And like clamping, it has not made my schlong permanently darker so far.

I basically follow the directions to the “T” that CaptnHook wrote, using a wrap and everything.

Is there a way to hang and have little to no discoloration in the glans?
Even if I make sure my glans has as little blood in it as possible it still gets this way. And I’ve tried positioning the clamp and Wench at different positions on my shaft with the same results. Or, should I just expect a certain amount of darkening?

Nevermind. I figured it out myself! Sorry for posting such an easy question to figure out.

Turns out I was doing the wrap incorrectly (thanks Bib for your detailed images). Also I was clamping on too tightly.
