2e message, est-ce normal après une érection ?

my glans get really dry and wrinkled as shown in this pic , am starting to think steroid cream i used has caused the skin to go like this

Were you given the steroid by a doctor or a dermatologist? What is the name of the steroid? Is it a white cream or a clear ointment? How long did you use it for?

it was hydrocortisone and just over a week

Irrespective of strength it is extremely unlikely to have caused any problem.
The whole idea of steroid applications is that they either help to eradicate a problem on the skin, or enable skin to become healthy again
