Hello i am 29 years old. A month ago i found out that when i pulled back my penis foreskin, the 2 veins right under my penis head were shaped like lump. It is not painful or irritating. But i am sure it was not there before. I am concerned now that what it could be. I always have protected sex. 

By the way, i went to 3 different urologists who say it is nothing to worry. but they seem that they do not know or have never seen a problem like this before.  I could not go to these urologists with erected penius. As it could be clearly seen when the penius is erected. When it is not erected, it is visible but it does not look like problem. The thing is it has been like this for more than a month. It is not painful or irritating as they are my veins that shaped like lump. The shape has not been changed. Please help me. Thank you
