Why foreplay matters more in long-term relationships
The research
Sex researcher Emily Nagoski describes two systems that drive sexual desire: an accelerator (things that turn you on) and a brake (things that inhibit desire, including stress, distraction, and feeling emotionally disconnected). In early relationships, the accelerator is nearly always floored. In long-term relationships, the brake matters far more.
What this means practically: removing inhibitors and building context is often more effective than adding new techniques. Feeling emotionally close, reducing stress before bed, and creating space for desire to emerge matters more than novelty for its own sake.
Foreplay, in the broad sense, is everything that moves the brake and engages the accelerator. That process starts long before anyone gets undressed.
