Kissing is often considered a means to an end. It's how many couples kick off their sack sessions, but as soon as things start heating up, sensual kissing usually falls by the wayside. 'Some people think that sex is so full of pleasure on its own that kissing isn't important,' says clinical sexologist Dr Krista Bloom, author of The Ultimate Compatibility Quiz
(Healing Couch). And that's a shame because locking lips throughout the sexual experience (and not just at the very beginning) can make the pleasure skyrocket considerably. 'There are tons of nerve endings in your lips that stimulate desire,' Bloom says. 'Smooching before, during, and after intercourse can be extremely arousing and satisfying.'
However, not all puckers are created equal; the trick is knowing what mouth-to-mouth moves intensify each stage of sex. Luckily we've gone ahead and mapped it out for you.
