well, you're not one religion until you choose it for yourself. [kind of contradictory from the whole 'born christian, therefore christian' most were raised] don't be so quick to label yourself, i spent 3 years soul searching and studying world religions until i discovered Wicca, and after that i did the typical year and a day thing before i started calling myself Wiccan and dedicating to the Lord and Lady.
take time to meditate and journal, figure out who you are and what you believe. i suggest making a list of beliefs [killing is wrong, cursing is fine, no meat on friday...] when you feel satisfied with the list, put it away for 3 months then take it out and edit it with any new information you might of discovered, and put it away again. repeat this 4 times until the year is up and by the end you should have a pretty solid list of beliefs you can use as a personal code of conduct. [you can edit this list as you get older, but i wouldn't edit it too much otherwise they're just words, not personal facts of life]
you might also wish to make a list of questions and views about Wicca and what draws you to it. you might discover it's the right path for you, or perhaps a similar pagan path is. research and ask questions, best of luck to you.
