Thank you for your question. I generally recommend waiting until all the swelling is down before engaging in sexual activity if it was just a breast augmentation. So typically two weeks would be fine. However, I would wait closer to six weeks with a mommy makeover as the abdominal region requires more healing before it can tolerate more strenuous activity.
Since sexual activity varies from individual to individual and because mommy makeover is very as well specific instructions can come only from your own surgeon.
