Hmm i've got a little problem here... The head of my penis is like 80% redish/pinkish but at the bottom of the head its like violet. Any1 know why?
That's quite normal. The head has extra thin skin and it's coloured by the blood in it. Blood with a lot of oxygen in bright red, but with less oxygen it's bluish-purple. It seems some of yours has less oxygen than the rest, but that's not something to worry about. The penis is very well supplied with blood, and the whole head can be purple without any ill effects.
