Open sexual communication is the ability to talk with a partner about what you want, what you don't, and how a moment felt — without shame, defensiveness, or fear that the conversation itself will be punished.
It is the willingness and skill to disclose sexual preferences, boundaries, and reactions, and to receive a partner's disclosures without retaliation or collapse. Researchers split it into the content of disclosure (actually telling your partner what you like and won't do) and the quality of the exchange (whether it feels safe and mutual or tense and one-directional) — and a couple can technically trade information while one partner dreads every word. It is not the same as sexual frequency; in one study of young couples it was communication, not frequency, that predicted relationship satisfaction 9. Nor is it consent alone (the floor on which this house is built), nor general communication skill, since sex carries a particular freight of vulnerability and inherited shame.

The Interpersonal Exchange Model explains why through two pathways: an instrumental one (your partner learns what to do) and an expressive one (disclosing something intimate builds closeness, which raises satisfaction) 3. The Gottmans note that only about 9% of couples who can't comfortably talk about sex report being satisfied overall — a vivid illustration of a well-replicated direction rather than a precise constant 4.

Why it matters
Why it matters. Nobody can read your body without instructions, and most of what makes sex good for a particular person is idiosyncratic. To tell someone what you want is to hand them a piece of yourself that can be fumbled or mocked; when it is received well, the relationship banks trust that generalizes far beyond the bedroom — and lets a couple adapt as bodies and desires change.
How to cultivate it
How to cultivate it. Talk outside the heat of the moment, trade specifics over verdicts ("more of that" beats "you never"), agree in advance how to decline gracefully, and meet honesty with "tell me more" rather than defense.
The honest caveat
The honest caveat. The evidence is strong on association and thin on causation — satisfied couples may simply find it easier to talk, and the two likely feed each other 5; effect sizes are moderate 1; much of the how-to is Gottman-tradition practice wisdom 4; and talking is no promise of fixing a genuine mismatch — sometimes its real gift is clarity.
