Even if that latter category sounds appealing to you, remember that people blithely (or desperately) looking for a squeeze between the sheets can put more earnest daters off.
The profusion of kinky folk can get fairly terrifying at times, especially if, like me, your sexual appetites are fairly tame.
One woman sent me an email with a five point list of things she wanted to do to me.
As few people actually bother deleting their profile, part of the torment of using OKC is wondering whether the person you've messaged is ignoring you or simply met a lovely bloke six months ago.
Mind you, it’s not all bad – there are plenty of lovely women on there, and the site has a huge success rate in matching partners.
All you need is an email address and a (hopefully charming) username and you’re reading to get creepin’.
Regular members can filter potentials based on a variety of criteria, which allows you to cast your net as wide or narrow as you like.
The other reason all these people are on OKC is, of course, that the site is free to join. Well, yes, in my experience of online dating, free is very definitely bad.
And it's here where you encounter the second major drawback. Free sites are packed full with spammers and scammers and people looking for casual sex.

Ok Cupid (OKC) stands out because it is one of the biggest dating sites out there.
