But radically traditional or not, kissing doesn't get much glory in the world of sex. It is seen as sweet and modest rather than down and dirty. It can get lumped together with "foreplay," that vague category of activities that's ultimately supposed to lead to intercourse. Or it's considered something to skip altogether: According to the study, more than 50 percent of men said they would have sex with someone without kissing them, compared to only 15 percent of women. That's one of the stats where gender differences were extremely clear. Porn stud Jack Lawrence echoes the split: "You can tell if someone is a good lover or not by how they kiss. . . . Kissing is an art form . . . if it comes from the heart, you can express yourself and understand exactly what a lover wants in bed. . . . It's all about passion and being able to read a kiss. It's funny how most women understand thatand, from what I hear, most men don't!"
