Talk to your doctor, he can prescribe a cream that will makie retraction a lot easier with continued use.

Wait don't go to the doctor yet. I had the same problem. You just have to use some kind of lube (even soap) slowly retracting it slowly back and forth. Do that every day and you'll propably be ok. Stop when you feel too much pain.
And don't have sex if you cannot fully retract it behind the '' head '', pain will kill you.

But how long will the soap(i dont possess any lube) method take?

Will it still hurt if I wear a condom?

The lotion, with time, is suppose to make it so that it will always easily retract. Lube really is only a simple, temporary fix.
