Hi sawyer, would your first name be Tom.
OK I think the red line you see is just a vien, and the reason it come out more is that you agrovated it, your p***s being stumpy, I think you will find that you a grower, and you ask what is a grower, 2 men 2 p***s when erect are 6 inchs, when slack one has 4 inchs and the other or you has 1 1/2 inchs, hence growers and showers OK.
Your foreskin try and strech it by pulling on it, its ok it wont tear or full of, but make it bigger, so it goes back easyer.
And the red/perple skin is caused by lack of oxygen under the skin.
Do hope this helps.
But see your doctor to confirm.
Good Luck
