My girlfriend believes too much fondling will move the implants and result in misshapen/ ruin breasts. Is this true?

From a medical standpoint, we advise that it is safe to handle/manipulate the breasts after 6 weeks and assuming there have been no complications. The breasts should be well-healed at that point and regular activity/handling can be resumed if the individual feels comfortable.Hope that helps

This question gave me a chuckle at first.Let me start by saying that the decision to undergo breast augmentation is your girlfriend's choice, not yours. In no way, should anyone be persuaded or pushed into surgery. Breast augmentation can dramatically change a woman's appearance. Most women love the look, but some can be devastated if they are doing it for the wrong reasons.Now, to answer your question...After one month, gentle "fondling" or squeezing is fine. They can be treated as natural breasts and there really is no risk from "too much" after 6 weeks.I hope this helps.- Dr. Bryson G. Richards, MD

Typically it is reccommend to abstain from sex for 6 weeks to ensure the implant has settled. After this point this should not be a concern given everything with surgery went well with no complications. 

Each surgeon has his or her guidelines for postoperative care. Typically, surgeons will advise 4 to 6 weeks post surgery to abstain from sex. Consult with your girlfriend's surgeon as he or she knows the scope of the surgery and the specifics about you.
