No-strings sex with a stranger can sometimes be hard to find, despite the large number of horny singles sitting at home on a street near you right at this very moment. Fortunately, the internet provides each and every one of us -- no matter what our looks or charm -- with the opportunity to "sell" ourselves online to a suitable (or completely unsuitable, as the case may be) woman, man or “other.” Finding casual sex partners is now far easier than ever before, but don’t get complacent; you have some hard virtual yards to cross first.
