Stretching question

So I’m trying this novel way of stretching similar to the ADS using string, cloth and tape. It’s actually giving a nice firm, but not too firm, tug on my member. But I was curious, if my member starts to feel cold does that mean it’s cutting off too much blood flow? Or is this OK as long as I don’t leave it on too long?

Cold = BAD

It means you are cutting off precious blood and oxygen. Not good. Cool is ok, cold is not.

I would stick with just using your hands for the time being until you are more familiar with the process. Repeat after me: I have one penis, I will not hurt it. Say 50 times a day and follow the newbie routine. IF you injure yourself, your goal to get a bigger dick will be delayed and will frustrate you, please don’t hurt yourself.
