Unable to pull back my penis foreskin.

Hello Doctors, I am 25 years old,but lately I am unable to pull back my penis foreskin. Through different articles, I got to know it can be termed as phimosis (I am not really sure it it is so) Because phimosis states, a person could feel while urination, Pain at the sex time, but in my case there is no pain in both the cases. It is just quite hard to pull back my skin, even If i try, it won't pull back. So here I need help with, Is to possible to cure now? If yes, what are treatments available (Non surgical first and thn oy Surgical) Sometimes I do think, Due to this even I can sense Erectile Dysfunction and Premature Ejaculation. Can someone please guide me, How to cure this problem efficiently. I really want to get rid of these. Please suggest me some medicines,Gel, Cream(If Any) Looking forward for the support from Doctors. Thank You.
