Foreskin tighting and glans sensitivity.

I'm 22 year old. My penis foreskin is very tight, i didn't even know that foreskin was supposed to be pulled back a year back, at that time foreskin was so tight that i will not pull back a little bit.. So i tried to slowly pull it back and now when my penis is not erect it easily get pulled backed but when penis is erect it gets very tight and also the inner part the glans is also very sensitive i cant even touch it, this make my sexual life very hard as every time i try to put condom on it i loose my erection or i ejaculate very easily. I consulted a doctor on practo itself he recommended to go for circumcision. Can i get this resolved without surgery. I searched that it can be cured with seriod cream and medicines for foreskin and glans. Pleade help.
