When you start dating someone new, there's always the question of when you'll be sleeping together for the first time. In popular culture, the third date is often seen as the appropriate time to become intimate. This is known as the three-date rule, which was famously practiced by Charlotte York in Sex and the City. According to Concepción, this rule has to do with setting clear boundaries and expectations.
The three-date rule is, in a way, a commitment. Waiting three dates tells someone who needs emotional security that their partner is interested enough in them to invest time and energy in going out with them. But it's not too long for the person who might be happy having sex on the first date. Ultimately, the three-date rule is up to each individual couple to decide.
Some may choose to wait longer than three dates before becoming intimate, while others may decide to become intimate sooner. It's important to communicate openly and honestly with your partner about your expectations and boundaries so that you can both be on the same page.
