Newbie stretching

Hey guys im on my 5th day here....IM doing the beginer routine and i had a question with the stretching...is my head suppose to go blue while doing the stretches?

How long does it stay blue?
Intense stretches for a very short time-10 to 30 seconds or so- shouldn't give you much trouble at all as long as you massage the bloodflow back into your penis at every opportunity.

One prominent theory propounds that a man's natural nocturnal erection cycle is mostly to keep proper blood (hence oxygen and nutrients) flow into an otherwise "dead" penis.
And I don't think anyone wants a necrotic cock.

Remember: bloodflow=healing, healing=growth.
P.S. Have a look at my sig...might give y'little help.

It only stays blue for a little bit like while im stretching...then its fine...

Thennnnnnn.....it's fine!
