They are not going to let some picture on the site.  But what you are telling me seam normal.  Vein on the penis can com up at any time.  I have a very big vein on my penis I have never notice it when I was younger but it is fine.  I don't know if you have ever watch porn I have seen some with the men that have vein under the head.  Remember we are all different and we are made different.  If it does not bother you I would not worry about it.  The penis is made up of a lot of vein.  Some come to the service and some don't  Take care  Ken   

I only can online using phone. It's not a vein but a lump/inflammation shape like a vein. It's not blue. But like skin coloured.

Moderator comment:I have deleted the links to the images as they went to a site unsuitable for inclusion in the forums. Users can upload images directly to this site by using the icon at the top right of reply boxes.

I was made aware by one of the members that this does not work on iPhone, but if you have a Android Phone you may be able to post a picture from your phone trying this....

You can also post pictures with your phone's web browser. Example... On my Android phone I would open the site in your Chrome Browser and in settings drop down menu select request "Desktop Site". Desktop version will load and you are now able to attach pictures to you post as if you were on a desktop.

Note: you may have to scroll sideways to find the picture attach button. 

Buddy it does look like a vein but if it does not bother you it fine.  You may have been holding your penis to tight when you were masturbating there are so many vein in a penis.  Be safe  Ken
