Erectile dysfunction and hypertension.

Hello Doctor, I have dark patches and dry skin like patches on my glans. It's been there for 2-3 years now and size of these marks/patches have increased slightly over the years. And also I have problem in maintaining an erection while intercourse. I went and consulted a sexologist a month back, she said I don't have to worry and prescribed Efficort Hydrocortisone Aceponate Lipophilic Cream(Apply only at night before I go to sleep for a week), Venusia Moisturizing Cream(Apply thrice a day), Ranbaxy Caverta 25mg and Antoxid HC Tablets for three weeks. So far, I don't think it worked or works. Again, I consulted a Dermatologist online, he said this is Hyperpigmentation. I don't who is correct. I'm confused and I need help! Can I undergo any surgery or laser treatment to get these removed and my glans back to normal? I WANT THESE REMOVED, PLEASE HELP! Also I lost that prescription and I'm going out of town this weekend so please prescribe me Ranbaxy Caverta 25mg since I need it. Thanks :)
