@Venkat4111,
Are you near a good university hospital? I don't know how your hospitals work there, but here in the US, where there are famous medical school universities (also famous otherwise), they tend to have people on staff for many fields, such as neurology and urology, and so on; also clinics as well, not just private doctors. I have what I think is the world's best ophthalmologist, and I see him in a clinic.
On your fixation about masturbation (I commend you for spelling it correctly, many don't!), I 98% - think that is a red herring. It's a red herring unless you somehow broke/tore something back when you were eleven, twelve, and so on. Which causes me to ask if you have seen a urologist? Doctors are specialists for reasons and tend to read up more re papers in their fields.
Also, past that, the other symptoms, even if you tore something somehow back then, are likely unrelated - and you are conflating the two questions.
