This is not an unreasonable question, and the straight up answer is NO.Immediately after a tummy tuck, there is always the chance of bleeding secondary to increased blood pressure which occurs with both sexual excitation and orgasm. Muscle repair is 100% healed at 6 months, 90% healed at 3 months, and 75% healed at 6 weeks. Therefore, if you were my patient, I would not recommend sexual activity of any kind prior to 6 weeks. The spasmodic movements some people have during the crescendo of sexual excitation and the accelerated movements during orgasm can, at times, cause shearing forces between the rectus abdominus and the skin and subcutaneous tissue above leading to a potential space which might be filled with a seroma or hematoma.Once you have chosen one of the excellent Board Certified plastic surgeons in Dallas, you should pose this very reasonable question to him or her and get their medical advice.
I would say that you probably need to wait 3-6 weeks before considering this. You also need to limit your exertion early on as well. You are best to review with your doc.
