I am uncircumcised and I have never jelqed or PE'd at all.

My foreskin has a couple of veins on it I can see all the time. 1 large one that goes up and basically around my dick and a few others that are smaller (about 3 of them) so I was wondering would have a foreskin and/or veins help or maybe hinder gains at all? May sound silly to some of you but extra blood flow might do something, you never know and I certainly don't. Thanks for any responses!
