It means when your attracted to someone, not sexually, and you want to get to know them before you make love to them and basically hand over a big part of you. When you think of sex as something sacred and not just as a one night stand. This goes for both men and women. When men don't have shame to express feelings to a woman and when women truly like a guy and doesn't take them for granted.
