In fact, they’re not even exclusively for dating, as Ok Cupid allows you to be married or in a relationship but looking for friends.

(Riccardo and other Couchsurfing users quoted in this article asked to be identified by pseudonyms.) On the business front, the crowdsourced hospitality site has been experiencing a rough patch lately.

After a controversial transition to a for-profit model in 2011, which brought $22 million in funding in the past two years, growing pains have set in.

Riccardo G.’s profile on Couch Surfing.com, the website that partners intrepid wanderers with willing hosts, notes that he lives in the “best neighborhood to go out and have drinks,” that he offers a “cozy/clean/nice sofa/couch” and that he’ll even let you bring your “small dog, if you just can’t live without him.” He describes himself as “amazing, outgoing, funny, smart” and says his interests include friends, eating, drinking, the gym and puppies.

His photos show the good-humored Latin American native — dark, handsome, and fit — in exotic destinations around the world, from Cairo to Capri.

OKCupid (OKC) provides an algorithm that lets you score how important different questions are to you, which in turn lets you narrow down potential matches. At this point, their monthly fees are low compared to industry average.

Emails from potential scammers (IP address and specified city mismatch, I'm guessing) are flagged with a message warning of funds transfers.

But the key to finding the right site (or sites) for you depends on what type of relationship you’re in search of.

If you’re just dipping your toes back into the dating pool, free sites can be a great place to start.

Now that Valentine’s Day is officially over and you finished spoiling your girl with a fancy dinner, expensive gifts, and the best D you could muster after a long day of work and multiple glasses of the most expensive wine you could afford, you’re looking to make some time for the other woman (or women) in your life. We don't condone stepping out on your lady, but we're not here to judge. So, how does one go about keeping their scandalous ways a secret from their better half?

The only problem is your girl is like a new age Jessica Fletcher and checks your Twitter mentions, your Facebok activity, your Instagram likes, and, most importantly, keeps tabs your phone activity.

To help answer that question, keep the following in mind: Free sites are geared toward casual daters, while paid sites tend to be for people looking for a serious relationship.
