I allow patients to resume "cardio" after a week, and as long as there are no major acrobatics involved, some sexual activity is okay at that point as well. I know that some patients probably get busy a little sooner than that, and one recent patient who had bleeding the day after surgery let it slip that he had sex. My instructions for the first week are that patients avoid anything that causes a raise in heart rate or blood pressure, and sexual activity has that effect, so it's not a good idea. That said, you should speak to your surgeon for his or her recommendations, since he or she will know the extent and nature of your procedure and be able to guide you specifically.
