Solid niche for group sex fans
I've been on Sex Grupowy for over a year now. It is a Polish site so the language barrier is real but the intent is clear. I really rely on the advanced search filters to find couples looking for a third. That feature saves me from wasting time on profiles that do not fit my specific needs. The only downside is the recent price hike. It got annoying but I stay because the member base is active and genuine. There are fewer bots than on the big generic apps. It is worth the extra cost for what you get. I would recommend it to anyone serious about group dynamics.
