No comment on the "finding a reason" part of shaving legs things, as I'm living fulltime as female and just shave my legs whenever I wear a skirt or shorts, but if you do decide to shave them, you are in for a treat for the first few days. Your legs will be ultrasensitive and everything touching them will feel great. Since mine are shaved all the time, I don't get to experience that anymore, since my have become accustomed to being bare.
