I'm a swinger myself, have had beautiful swap experiences in past and in touch with few now too. Believe me it's amazing. Luckily, partner is like minded so in just the first conversation she was up for it.
There's a massive network of active swingers in India; right from the most elite ones to the most standard ones. These are all active on fb, cl etc everywhere.
Let the fantasies be lived and experienced, one life;live it all by enjoying it and making it worthwhile.
