In theory you can engage in sexual activity the day after surgery. Specially if the implant is not placed under the muscle (e.g subfascial) in which case you will have very minimal pain. However, it is important to: not have your blood pressure increased, which can cause bleeding and short or long term complications for the implant,not have the implant displaced due to aggressive squeezing.Therefore, I usually permit sexual activity a week after surgery with care and totally normal activity 6 weeks post surgery.Hope this helps,Ali Rıza Öreroğlu, MD FEBOPRASEuropean and Turkish Board Certified Aesthetic, Plastic and Reconstructive SurgeonIstanbul, Turkey
