One of the funnier blogs out there has little or nothing to do with sex. It's The Dead Guy: the cartoon. It's a conventional cartoon strip like "Peanuts" or the very marvelous "Jump Start," and worth reading regularly.
I always find it fascinating coming across folks who are living the Beyond You & Me story. One of them is Stiletto Diaries, the story of a 20-something woman in Canada and her two male lovers. There's plenty of drama, and frankly, I'm worried about Stiletto Girl, because she's very young and her husband doesn't appear to be too happy about her love affair with a younger man. But I wish them better luck than Cassie had, since they're both about the same age (23 vs. 24).
In terms of younger lovers, you ladies should check out Mike at I'm Not Touching You (see above photo). Alternately funny, gross, inventive, crass and horny, he's a typical young guy with sex on the brain who also writes well.
And speaking of writing, there's Adrie Santos: the Accidental Sex Writer. She got the name because her smut is selling better than her regular writing (I can relate to that). She posts about a variety of interesting topics, both related to the printed word and to life in general, including her stint as a sex toy reviewer.
