How to make skin on penis softer

I have a mild skin condition which i'm using topical steroids for on my balls an penis. The doctor hasn't said what it is, although i've seen him quite a few times about it over the year and a half that i've had it for. On my penis it's just a small area on the underside which is effected but it's made the skin on my whole penis has lost it's elasticity and feels dull and rubbery, and so I have lost a lot of sensation there. Is there anything I can apply to help restore it's natural, soft feel? Some thing i've tried allready: I have tried pure shea butter, which just made things worse. I've tried vitamin suppliments, including vitamin E. But I havn't tried applying Vitamin E topicaly yet. I allready take a cod liver oil suppliment I have tried a couple of moiseturizers. Please help, am desperate!
