Hanging, very tight or not too tight?

So after 6 months of doing PE I finally started hanging. I was hoping this would finally solve my problem of making no gains.

Anyway I made the Captain Wench that was highly recommended on this site. So I made the wench and it works ok. The problem I’m having is twofold:

1) It tends to slip down just a bit, so I have to put the cable clamp on very tightly.
2) When I put the clamp on tightly my penis starts getting a little cold, not much but noticeable.

Is that normal for hanging? To lose a little bit of heat?

Hard to say how much is ‘a little bit’. If your glans doesn’t become dark you should be fine. How much weigth are you using?

only 2.5 to start off, I’m gonna up it to 5lbs after I let my penis get used to it

Sounds ok. You shouldn’t feel pain, nor your penis become darker.

Also, capitalize first letter of sentences and use other basic grammar rules, or your penis will not grow. (:
