It's a group in Turkey teaching woman to train their pelvic region to prevent issues as they age (Think of Kegel exercises). At first look one would think about those "tuppersex" meetings where new sex toys are being shown to women.
Just use reverse image search, there was a page in Turkish (teyit.org) clarifying what was all about.
Sorry if this sound like a redditor correcting people...
