Good afternoon. On the bottom side of my penis I see "light, transparent" veins ( for about 2 years I thought that they are veins that go to the head of my penis) - they are about 5mm long on both sides of the bottom of the penis head. They were the same size till about this time, but now I started to see that from right side it goes more to the middle. There is no pain. I'm wondering if it's normal, or not. I didn't have sex for about a year already, but I'm masturbating quite a lot.
Here you could see the pictures:
