Dear Dr, i m a malaysian. 8years ago, an olive oil was injected in my penis skin. Reason is to enlarge my size. That time i was young. Been influence by others. So i did it. Now the problem is, my skin in the front part is become thick n rough. I cant even pull down the skin to wash penis head. But when im in sex, no prblm at all. What should i do? If i come for treatment / operation, how much does it cost?
