A woman's body is a very beautiful thing. Its not only beautiful but interesting. I myself am 5'2 and weigh 134 pounds.
Although you should never starve yourself. Trust me its not worth it.
Its cute when you have some fat on you. I preferably hate when others call people fat. Your not fat so don't think it.
Shave only when you want to its your choice.
If you want to lose some weight you could cut back on unhealthy foods such as chips and sodas. You could prepare you daily meals. You should exercise for an hour a day maybe more. Going on jogs is also fun. Just don't starve yourself.
Be proud of who you are.
