Best Reconstructive Urology doctors in Kolkata

For a urologist: Hi, I'm 16 year old male, I have phimosis and hypersensitive glans, Recently I brought betnovate-n to lossen the foreskin but how do I apply it without syringe? Do I just pull back the foreskin to where it starts feel uncomfortable, that way the cream will definitely get on the glans and over long extended period of time, won't the cream start to do harm to the glans? Do I apply it when I have erection? It is harder to pull the foreskin back when I have erection, and can I urinate before or after applying the cream? Does the foreskin and glans have to be dry before applying the cream? I brought the cream without a urologist's diagnosis since I live in a traditional village without access to such things, not to mention that I don't have the type relationship to anyone in my family where I can talk about these things, so I did bit research and I definitely have phimosis grade 3-4(I can barely see the glans when i have erection) I came across article which said that steroid creams can thin the foreskin to the point where it will rip apart, so I'm very scared and nervous. What's the chance of that happening? Ignore any grammar mistakes as English isn't my first language. Thank you very much.
