Ben this looks like a normal blood vein to me - these can be really prominent in some males, particularly when the penis is in the fully engorged stage of an erection.
If you want to put your mind at rest get the Doc to check it for you - as, you would need to get a Doctor to put treatment in place if it was Mondor’s …
it feels normal no pain nothing i have for this thing at vein looks like something under the skin when i stretch the penis up but idont know what ot is i spoted before 15-16days maybe it was before
Can only suggest you get Professional Medical advice …
