Mons pubis is large puffy and ugly after FTT 14 years ago. Worried about long term post-op numbness and more scarring. (Photos)

Thanks for your question and photos.  
Abdominal contouring has continued to evolve and advance over the years.  Years ago it was not unusual for someone to have a full tummy tuck, like you did, with little attention paid to the area of the mons.  Today this should be recognized prior to surgery and be included in the operative plan.  I routinely perform liposuction of the mons when doing abdominal contouring and in some cases direct excision of the excess skin and soft tissue.  
From your pictures I would agree that you have significant excess skin and fat in the area creating a less than ideal shape.  All is not lost!  A simple revision with excision of the excess skin and liposuction to smooth the overall contour would be a viable option.  Should be much less numbness and scarring when compared to your original surgery.
I would strongly recommend an in-person consultation with a plastic surgeon to investigate your options.
Best wishes.
