My penis glans became yellowish which looked pale when erect nearly 2 months ago.I guess Its not due to bacterial or fungal infection because i had taken antifungal,antibiotic tablets such as fluconazole, tablet azee,used fusidin cream,lulifin cream,kz cream,as per a doctor s recommendation but there is no improvement.I think the problem is due to lack of proper blood supply.what are the medicines to improve blood flow.
