Yes ,it is a little expensive but I used a medical tourism company to help me with everything. I also asked for a private room at Fortis Hospital and extended my hospital stay because I was there alone: I wasn't confident to be discharged with a catheter. I had noone with me. The medical tourism company did everything.if you have someone with you, then you wouldn't need the assistance of medical tourism and your overheads would be less.
In relation to depth etc , I still am not sure as I haven't been able to measure my dilator yet. Regarding lubrication, yes I self lubricate. I use lube but don't need to use much. I don't know what it feels like inside( haven't tried my fingers yet) but when I slide the dilators it, it feels kind of moist, soft and kind of a muscle feeling. I am still very much healing so I can't give more information right now.
