The Prehistory of Sex
The Prehistory of Sex is one of those books that makes its point by somewhat overstating the evidence (if you see what I mean). Taking things a step further than you really should, in order to make people re-think their entrenched positions is a well-established thing to do, and I think that's what's being aimed for here. People are so used to thinking of prehistoric people as only having very functional sexualities that lead to more prehistoric people that it's a good thing to explore all the possibilities, even if you're reaching beyond the evidence a bit.
An example is a figure on a Iron-age cauldron which has a dude in an unusual position; you could make a case for it being sexual (though personally I think he's just got his legs crossed), but the author says it's a Tantric Yoga position. That's reaching a lot. So you can make your mind up, here's the chap, from the Gundestrup cauldron:
A good interesting read, if you take the reaching beyond the evidence into account.
