Masturbation After Tummy Tuck?

Hiya. I'm a guy that recently had a tummy tuck & removal of excess skin in the breast & two incisions around the pubic mound that are connected to the "belt scar". About a week post op, but I've been having erections just as frequently, and morning erections starting 2 days post op. I'm not sure if it's healthy to maintain the erection, so I usually wait until they disappear. However, I feel the urge to masturbate as well during the day, but am not sure if it is safe. I can wait, but should I?
