OkCupid is by far my favorite of all the sites Ive tried and Ive had the most success on it despite currently being single. It offers options other sites dont like narrowing down your search criteria to specific groups and types as well as giving a person the freedom to choose between a variety of sexual orientations and preferences. It may not seem like a big deal to most people, but other sites flat out exclude certain groups due to their lack of options. Im not poly or in an open relationship, but some people are and not all of them are swingers for god sake! If you are looking for a site thats not as vanilla as the mainstream dating sites and no where near as hardcore as some others, OkCupid might be a good choice for you.
