Foreskin gets tight and non retractable.

I was having a normal penis,with foreskin gets retracted during sexual intercourse,not usually retracts during urination and all.But suddenly after a infection it's not getting retracted,infection is cured after consultation and medication.Is this a real case the foreskin which was working fine will it get hardened in between.is there any lubricant which can help in retracting the foreskin.Will all fungal infection lead to a stage like this...will this be cured by time..is surgery only option...any lubricants and creams are helpful in this.Now all my infection issues are solved no scars,no swollen skin and no reddish colour even no itching also after taking medication..I can see the glan but the foreskin no sliding down exposing the glan
