BiCupid.com is a site for bisexual men and women. The members' database might not be as deep as other sites, but that's to be expected. Nonpaying members have limited browsing options, because they can only search within a 100-mile radius. More importantly, only a month’s paid membership will allow you to see when members last logged on, which is very valuable information for determining whether a site is worth joining in the first place.
