How long after BBL can I resume sex?

After a Brazilian Butt Lift, usually you can resume sex within a week or so depending on how your healing is progressing and when you are comfortable doing so. It also depends on what specific procedures you had done as well as how your recovery is going.
Obviously the body heals with swelling and inflammation and usually that maxes out at two days and then starts getting better. Most of these patients take no pain medicine (because of the nerve blocks given during surgery) and usually feel very comfortable going out in public the same or next days.  I usually call my patients the night of surgery and check on them in person the next day. If everything is fine the next day, I then let them shower and they do not need a dressing over their incisions. At the two week check up, I usually have people start working out and then after six weeks they can do whatever they want. 
I routinely tell people to take a few days to a week off work and to hide out but some people are very nervous especially celebrities and they might hide out for two weeks. As with any scar on the human body, initially scars are red, hard and raised and it typically takes six months to a year for them to become a soft thin white line. 
Additionally with recovery, there're many things we do to expedite healing such as nerve blocks during surgery, oral supplements, skin care and scar therapy recommendations, lymphatic massage sessions that are included in our pricing.
I strongly feel that it's very important to have an honest conversation with your surgeon about your particular situation, lifestyle, work environment and specifically which procedures you're having done so that you both have the most honest answer about your recovery and are realistic with expectations and results.
I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS and performs a lot of butt lifts.

Brazilian Butt Lift recovery time is dependent on how the patient’s body reacts to the procedure. Patients usually return to work after a week but you should not sit without the use of cushions for at least two weeks and you must wear a compression garment for several weeks after the procedure. You should wait until at least 2 weeks after the procedure to engage in sexual activity. Swelling and discomfort normally fades at six weeks. After about a month you will be mostly healed and you can get a nice idea of the permanent results after around six months. You should wait until at least 2 weeks after the procedure to engage in sexual activity.

Thank you for your question. Basically I tell women that they can return to sexual activity when they are comfortable. Usually patients can return to sexual activity after a week of the surgery, it also depends if any other procedure was performed along with the BBL.  That said, you definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety.  Best is a Board Certified Plastic Surgeon with specialized expertise in this procedure.

Dear appleseed82,Thank you for your question. After having lipo to harvest the fat for the BBL you will be swollen and with discomfort. This is the time when you don't want to be touch, it takes around 2-3 weeks. If you feel strong enough after one week is up to you. Best wishes.
