More, more, more

Veins. I’m a pretty veiny guy. Stemming from the 5.7% body fat and a family history of giant veins, I’ve got veins like most people when the tourniquets on running down my legs not to mention my arms while working out. I’ve just noticed that I’ve got a some what veiny penis. I’d like to have more. Is this possible to enlarge/create new large veins?

Yes, jelqing and other PE exercises will accomplish this no doubt.

Exercising the arms and legs definiteley sems to promote more exposure of veins/arteries. Same thing probably happens with jelqing/clamping. Not sure about growing new ones that you can see with the naked eye.
