I know that it is a completely different part of the anatomy (not even the same sex!), but I am a urology nurse, and when we do a radical prostatectomy (remove the entire prostate) on a man, we tell him no driving for 6 weeks. The incision site is in the same lower abdomenal area, but is vertical, and we tell them no driving, because of the slower reaction that you will have trying to brake in an emergency when you have a painful wound right where the seatbelt sits. The effort of driving and moving your legs in those situations also puts extra pressure on the wound and can cause it to dehiss (open back up again) - and we have had to re-admit people to hospital to have dressings done, and for IV antibiotics when this has happened. And as this is something that can be avoided, I think you are just better off not driving for the 6 weeks, instead of taking the risk
