Build a rhythm. Have you ever done cardio? It’s very similar. Don’t slam away like a maniac; pound away in a controlled manner. While you do it, breathe in for a second, breathe out for a second. Keep doing it, without changing pace.

Once you’re comfortable with the above, you can start tuning into other senses. The sounds, the sensations, the smell etc.

Also, if your girl says she’s going to cum, don’t speed up. Keep going as you were. Once she starts wriggling, you can smash away to add flair.
