When considering your options, it helps to identify what your intentions are for using an online dating site. If you're not looking to meet your future spouse, you're probably better suited for the adult dating site FriendFinder-X, a place where you can live out your sexual desires and find others looking for the same level of casual commitment. FF-X is a strictly hookup- and casual sex-oriented site that boasts millions of users around the world, so if you're looking to get lucky, your odds are high here.
Age-based niches: These sites are for people of a specific age. Baby boomers are overwhelmingly turning to the web to find a mate. Sites like Match.com and POF.com offer members a chance to search specifically for the age group that interests you, but SeniorPeopleMeet.com and OurTime.com are the two largest sites designed specifically for the baby boomer market.
