Hi there. Thank you for posting your question with Healthcaremagic. I will do my best to help you.
Your "friend" can not have phimosis
from childhood since he would need to be at least 20 years of age before this diagnosis can be made. That's the first thing.
If this is true phimosis your "friend" would need to be over the age of 20 years and not be able to retract his foreskin over his flaccid glands penis. He would also be having recurring infections around his foreskin with cracking.
If your "friend" is not all that bad then he could try some antibiotic/steroid
cream like Fucidin
H to give some temporary relief. But if he is as described above, then the only solution is circumcision
I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.
