8. Cuddling With Cranial Ridges

Are you a cuddler? Do you long for lasting closeness with your partner? Yeah ... not with a Klingon. Given their cranial plates, ridges, and the reinforced nature of their endo-skeletal physiognomy, you'd experience greater success canoodling with a cheese-grater. Klingons are built for combat not cuddling. If you're from the city of Glasgow, where head-butting is a form of ritual greeting, then Klingons are well-equipped for life in Scotland. But if you're someone who requires the reassurance of personal, physical contact from a partner, you'd be best advised to look elsewhere. Klingons only touch each other when there's an assurance that hand-to-hand combat will ensue. Even in ... intimate moments, Klingons don't try to pleasure their partners they try to intimidate each other. Thankfully, in the 60's, we didn't see this aspect of Klingon life, but when B'Etor tried to seduce Picard in TNG 's "Redemption", she began by growling in his ear and sizing his head up with her taloned fingers like it was a melon she was going to devour. Even poor Jadzia Dax in Star Trek: DS9 was covered in bruises after a tryst in the holo-chamber with Worf. That isn't love that's a self-defence class for masochists.
