(UPDATED 3-26-09) - As promised, I have updated my review of AdultFriendFinder.com, and I'm going to tell you how to get a FREE Silver Membership! Since the last time I wrote a review of their service, they have added several new features, such as unlimited downloadable adult videos and live webcam models available for chat (a la Cams.com). I've also taken a more thorough look at what they offer for their free membership, and I've discovered a way to get a FREE Silver Membership for two weeks, and it's totally legal. It's not a trick or a scam. Read on for details.

ALT.com is the world's largest BDSM and Alternative Lifestyle Website.  With  membership of over 3 and half million, finding like-minded people, probably right in your own backyard, is a very good possibility with ALT.com.

They are a bit stingy with the features for the FREE Membership, but they more than make up for it with the Gold Premium Membership Package.  In fact, their Gold Package is currently the same price per month as the Silver Premium Package, and you get more than twice the features and privileges with the Gold Package.

Amigos is the Ulitmate Latino Online Dating Service, with over 6 million active members worldwide.  Another member of the Friend Finder Family, Amigos.com is, for all intents and purposes, the Latino version of Friend Finder.  They offer an option of either a Spanish, Portuguese, or English interface for members.

With over 7 million members, Asia Friend Finder is the World's Largest Online Dating Service targeted toward Asians.  The site offers an English interface, as well as a traditional or simplified Chinese character set.

Ready to seriously get your kink on?  For experienced BDSM players, Bondage.com offers a community experience quite unlike the other Alternative Adult Online Dating Services.  In addition to personal ads, they offer a large selection of Bondage and BDSM articles, erotica, pictures, and video.  They also have both standard text chat, as well as Audio/Video chat.

Are you feeling creative?  There is a bonus, not heavily advertised, in the Erotica Section.  If you submit a story to Bondage.com, and they publish it, you will win a 3-month FREE Premium Membership.  If they publish more than one of your stories, they will give you a 3-month FREE Premium Membership for EACH story.

If you want to see some of the hottest men and women on the 'Net, performing for you live on camera, check out Cams.com.  Or, if you want to perform for them, or with them on their Cam2Cam system, you can do that too.

You can join in live nude chat with the models, make them perform exactly the way you want them too.  You can also watch thousands of pre-recorded shows of the models.  It's really the perfect solution for the person who wants interaction with someone, but isn't quite ready to get out there and meet people.

(UPDATED 4-29-09) - Date.com has recently undergone a major facelift.  Once the premier free dating service on the internet, they now restrict most of their good features to paying members.  Established in 1997, they have helped thousands of men and women get together.  You can join now for free and start finding men or women near you, or search around the globe for your perfect match.

This site is THE LARGEST ONLINE DATING PERSONALS SITE for Filipinos and people interested in the Filipino culture. The site uses Filipino character sets as well as an English interface. Membership includes people from around the world, with a high concentration of Filipinos residing in the United States. 

A valued member of the Friend Finder network, Filipino Friend Finder continues the model of creating online dating networks to help people of certain ethnic backgrounds to not only find other people with similar backgrounds, but also to give them the option of using an interface that is available in their native language.

(UPDATED 4-2-09)   Fling.com is one of the most popular adult dating services on the Internet right now.  Fling.com is on par with the other adult dating service sites as far as features are concerned, but you have to be a paid member to enjoy most of them.  Their membership database is relatively small compared to other popular adult online dating sites, but their prices are very competitive compared to other similar services.

Additionally, they offer a 3 months FREE guarantee if you aren't satisfied after 3 months of their service, so that's also a big plus. And, the site is relatively easy to use and navigate, and joining is easy and FREE.

If the relationship you're looking for isn't necessarily sexual in nature (or at least not completely), Friend Finder offers a great alternative to the Adult Online Dating Services.  This PG-Rated site offers all the same features as it's big brother Adult Friend Finder, but without the nudity or adult content.  They claim to be the largest Online Dating and Personals site, but their membership of just under 2 million is significantly smaller than the membership of Yahoo! Personals. 

Looking for a same-sex relationship, but not quite into the hot, steamy gay sex scene?  Gay Friend Finder is the PG-rated version of Out Personals.  You get all the same features, but without the nudity and adult content.

Brought to you by the same folks that have brought you Adult Friend Finder, Friend Finder, and ALT.com, GayFriendFinder.com offers basically the same features and interface as those sites, but with an exclusively gay, PG-rated membership.  You can chat or IM with other gay men or women, read member blogs, and view live and recorded video introductions.

Gay.com is one of the largest gay and lesbian online dating site with over 3 million active world-wide members. In addition to online dating, we also offer other gay community related information, entertainment, live chat, live video chat, photo library, news and much more.

IwantU.com also offers several features and services that many other Adult Online Dating Services do not offer, such as an online store, Video on Demand, and even an escort service. Now, if your primary goal is to get together with someone, these features may not be anything more than a distraction to you, but if you are interested in low priced streaming video porn, IwantU.com is certainly worth the money, especially with Premium membership for as little as $14.95/month for a 90-day subscription. They also offer a 3 months FREE guarantee if you're not satisfied within your first 3 months, so that's a real bonus, as it effectively cuts your monthly subscription rate in half. This is especially good if you're into the streaming video and escort service that they offer.

For those seeking to satisfy their kinky side, IwantU.com now offers an Alternative Dating Club.  With over 7 million members worldwide, IwantU.com has one of the largest membership databases of any Adult Online Dating Service, making them a good pick for actually finding a date. They offer advanced search options, where you can search by location, preferences, and sexual orientation. You can also contact members via email, in chat rooms, as well as send them "IwantU's", similar to winks on other site. 

Looking for more of a feminine touch?  LesbianPersonals.com is an online dating service strictly for women looking for other women.  Yet another member of the vast Friend Finder dating network, you get all the same features as with Friend Finder, but the membership is stricly women.

(UPDATED 4-28-09)  Match.com is the world's #1 Online Dating Site, with over 15 millilon members worldwide.  This number is in fact less than half of the membership of Adult Friend Finder, which goes to show that having the largest database isn't everything.  Nevertheless, it is an impressively large database, so you have a great chance of finding love, whether you're looking for the boy/girl next door, or you're willing to look on the other side of the world to find the love of your life.

Additional features include the option to receive new match updates on your mobile phone, a portrait-refining section, and detailed search capabilities.  They also now have Happen Magazine, which offers good tips for starting (and keeping) a relationship.  Click Here for a Sample.  Match.com also encourages you to complete a good, honest profile to help you find your perfect match.  In fact, their current 6-month guarantee depends on you having a completely filled out profile.

Out Personals is the world's largest gay personals site. More than just a gay personals site, Out Personals offers an adult environment geared toward those looking for hot man-on-man action, fantasies, and straight-up sex, as well as romance.

(UPDATED 4-10-09) SexSearch.com is a great site for finding a casual sex partner. Even with a smaller database (21 million members) than Adult Friend Finder's 31 million members, your chances of finding the sexual encounter you're looking for are very good at SexSearch.com.
