White dry patch on penis skin. Is it fungal or sti?

i had a dry white circle patch on the penis skin on monday. Now it is not visible almost mixing with skin color. there is no blister or syph like open skin. if i scratch on it lightly, i do not feel my skin. it is like the entire circle is deadskin. the whiteness disappears if i apply antifungal cream or of it is wet. the insensitive skin however, does not go away. the doctor as usual asked not to worry about it. should i consult another doctor?

its more than likley a fungal infection or some kind of skin problem if u have anti fungal cream id give that a go if u see no improvement within 3 days to a week or it gets worse go to a doctor

stds dont cause dry skin patches it usually a sore or blister but yeast can cause the skin to dry and crack
