Apart from safety features and legality, it’s critical to consider a bit more intricacies. For example, swingers should choose apps focused on swinging and group sex. At the same time, such services might not suit singles into threesomes. Then, one should rely on desires. It means that, for instance, kink lovers will feel more comfortable on BeNaughty than on OkCupid. Thus, those having no specific preference and carving experiments will appreciate Pure more than Tinder.
