How sturdy are silicone implants under the muscle for bedroom play?

Implants are placed under great pressure when tested for safety. Literally tons of pressure are applied on an implant, and held there for a while, to see if they’re able to withstand it. The amount of pressure applied during sexual activity (even rough play) would not even come close to what is applied during testing, so you shouldn’t be worried about it. It’s more your actual breast tissue that you should be concerned about damaging.

1 month is a safe amount of time before the breasts are able to be used during foreplay and intercourse. IF you have no nipple sensation yet, then your partner can badly injure you, as you would expect, because the normal pain feedback is diminished. Make sure you have someone who is understanding of this and cooperative and safe. It can take up to a year for all of the nerve endings to wake up. Nipple numbness is very rare, though I have certainly seen it after breast augmentation. 

Breast Implants are the Timex pieces of implants ; They can take a beating and go on (ticking). Normal sexual roughhousing, ONCE YOU ARE HEALED, should not affect them in a material way. However, out of the hundreds of implants we did, we had a woman who had her implants flipped over by repeated rough manipulations. I would therefore wait until you are healed and have it it in moderation.Peter Aldea, MD

Implants are very stable and safe products.  Normal activity int he bedroom is fine once you have healed well.

While the implants are incredibly sturdy, they can rupture - usually for no reason other than "shell failure". So while direct pressure can result in rupture, it really only means there was a weak spot "ready to blow" anyway. I have had patients who even tie the breasts in bondage activity (you know what I mean if you've been there) and have had no issues. Handle as you wish realizing that implants may rupture but that is no reason to restrict your activities.
