But if you want to stick with it make sure you get a guitar that is comfortable for smaller hands. (yes, I'm making an assumption). If you don't have a guitar playing friend then visit several stores and tell them what you want. Don't buy after their recommendation, come here and ask first before buying.
When you start playing you're hands are going to ache for a couple of weeks to begin with. So you don't want to get discouraged and quit because of an ill-fitting or poorly setup guitar on top of that. More beginners quit because of that reason than anything else, especially females because they generally have smaller hands.
