Let pain be your guide and limit spinal motion. While there is no exact timeframe, we find most patients do not feel comfortable attempting sexual activity for a few weeks after neck or back surgery and some take longer. If you can walk a mile without an increase in pain, chances are you have enough strength and ability to control pelvic motion during sexual intercourse. Be willing to try positions that limit pelvic motion if this is painful. It may also be helpful if your partner assumes the more active role. Generally, however, side-lying positions are easier to control pelvic motion.
