In your romantic comedy, don’t have the hero and romance character jump into bed right away, just because you want something sexy to move the story along. They have to earn the opportunity to make love by becoming vulnerable in some way. They must let their guard down with each other, and experience real emotional intimacy before the physical intimacy. In the very few successful romantic comedies where the couple has sex before the midpoint (e.g. Knocked Up, What Happens in Vegas, Pretty Woman), it becomes a source of conflict that later stands in the way of their having a truly loving relationship.
