Whats a purple line down the shaft of my penis? -

I noticed I had a purple line going down my penis shaft down into my scrotum. In the middle of the purple line there is a red line im guessing its a vain. So what is this? Is it bad? I d appreciate some help. Thanks

You are right :it is a vein to pump blood into your penis to get hard. Sky.

yes, it s a VEIN. when the penis goes erect, the blood vessels are engorged with blood.
