Talking dirty, without trying too hard.
Done well, very arousing for many people. Done as a performance, not so much.
Dirty talk has high variance. When it lands, it really lands. When it misses, it kills the mood.

Three registers
Dirty talk shows up in three main flavors. Most people prefer one or two and find the third grating.
Three registers and one common trap
Most couples find their register among the first three.
Narrative
Describing what is happening or about to happen.
Directive
Telling the partner what to do, or being told.
Emotional and present
Stating arousal, attraction, or felt experience. Lower-intensity register that works for nearly everyone.
Performed crude (the trap)
Trying to sound like porn dialogue. The most common failure mode. Stay in your own voice.
What we know from research
The key variable is alignment between what the partner prefers and what is offered. Vocabulary range and improvisation skill matter much less than register match.
How to find the register
These are the moves most couples use.
Start in the emotional register
Lowest risk. Lands almost universally.
Test one phrase per session
Watch the response. If it lands, expand. If not, retreat.
Have the conversation outside the bedroom
Faster than another month of trial and error.
Avoid the porn voice
Stay in your own voice.
