I understand that in some hospitals it is very expensive to get a procedure. But if you really want the SRS Procedure in todays day an world, you can doing without joing any community or compromizing any other aspects of your life.
I would suggest you contact Mahatma Gandhi Medical College and Research Institute http://www.mgmcri.ac.in/
MGMCRI has been ranked 23rd among Medical Institutions in India by NIRF 2018. The cost of getting an penile inversion SRS there is minimal (less than 40,000rs approx) . And the surgeons there are very qualified & have experience of doing more than 100s of PI SRS already.
You need not join any community or compromise on any aspect of freedom of your life just to get an SRS.
