Stretching

When stretching alot of stress sems to be placed on the head. It gets very red aftr each stretch. Am I ruining circulation because the tip of my hed parts of it look almost white today and not flesh colored. ASlso any tips on manual stretching? I used powder and latex gloves for grip.

You shouldn’t place any pressure on the gland, the penis should be grasped behind the glans, 1 to 2 cm away.
Have a look at the following link for more info about basic stretching.
