Finally, the dirty bits. And they're pretty dirty. But as tempting as it is to giggle about the insane way that Lawrence describes sex in Lady Chatterley's Lover, we should also look at the way he uses it to express his philosophical ideas. This isn't 50 Shades of Grey: there's a lot more philosophy and a lot less spanking. Sex is a way—the way—for two people to connect. It fights back against the uncaring harshness of the modern world, and it restores some little bit of beauty and realness to life. Good sex gives you more than just bragging rights. It gives you wholeness.
In Lady Chatterley's Lover, the sex is secondary to the relationship. Connie and Mellors would have fallen in love even if they had never had sex.
D. H. Lawrence's descriptions of sex are gratuitous. The novel does not need such detailed renditions of the sex act.
