That tenderness, too, is a mark of Eros, and that sexual congress is a deeply human event. That the most arousing descriptions are the ones that are the most forthright. That bodies bump into each other in beautiful ways, and in violent ways, and in funny ways – and sometimes all at once. That no two people share the same desires. Sometimes seductive, other times salacious or surprising, these scenes – the very best ones – highlight a few undeniable truths. On some level, that's the genesis of both our fever and our delight, the blush of embarrassed intrusion rising to our cheeks and the glee that only that which is taboo can present. The most well-written sex scenes bring us into the privacy of bedrooms we are at all other times barred from entering. You're reading a book and then, sometimes quite suddenly, things get a little steamy.
