1. There are tons of nerve endings in your lips (100 times more than your fingertips) that stimulate desire. That's why kissing before, during and after sex can be extremely exciting and satisfying.
2. Forty percent of men say that a very long, passionate kiss will make them instantly ready for sex.
3. Watch out for those "see you later" kisses. If your man routinely gives you a quick kiss when he greets you, he may be on guard and doesn't express his feelings easily.
4. Men initiate open-mouth kissing to convey the testosterone spike in libido to their partner. So when he gets a little more aggressive, it's not just his desire - he wants you to be more in love, too.
5. A man is twice as likely to sleep with someone who is a bad kisser than a woman.
6. Passionate kisses raise your blood pressure and cause your heart to beat faster, making you even more excited, and making it easier for you to orgasm.
