When my penis is not fully erect or even mainly flacid, is it normal to be able to easily see the vein on the top of the shaft. It seems ugly and has been bothering my for some time. Thx.

I think it is normal. My husband also has a vein on the top of his shaft. Actually it is quite thick and sticks out quite a bit. I find it to be a turn on. There is nothing ugly about it.

Very normal, I have a large vein on the top of the shaft, you must remember that it's your blood that makes your penis erect
