As with good sex, a good sext tends to be in the eye of beholder recipient: if it gets you hot and bothered, well, then it's safe to say that it's pretty darn good.
Of course, not all sexts are, well, good. Take, for instance, the sexy texts catalogued by Best Sexts Ever—a blog similar to Texts From Last Night, but solely devoted to sexts. They may not get your engine revving, but they are likely to call up an embarrassing memory or two (or at least entertain you for a few minutes). Hey, those that can't titillate, entertain, right?
