If you have expanders put in---can you have sex?

Yes, you can have sex after having tissue expanders placed. I would suggest waiting until about 2 weeks after surgery and avoiding manipulation of the expanders. Please check with your surgeon to be sure that it's safe for you to proceed. 

Yes you can, but wait at least until the drains are out.  After about 3 weeks it should be fine.  Also I recommend minimal breast manipulation in this early period. 

You can have sex with tissue expanders in. I would wait a few weeks after your tissue expander surgery -  until the wounds have healed. As with any physical activity after surgery, take it easy when you start out!I hope this helps
