In my opinion, if you are asking whether you are Wiccan or not...then you are not Wiccan.
That's not to say that you could not become Wiccan if you wished to. But it's important to understand that Wicca is a very specific religion with specific beliefs and practices. You can read more about the core beliefs of Wicca at http://www.spellsofmagic.com/read_post.html?post=248610 One becomes Wiccan by deciding that they hold those same beliefs, and then does the work and study necessary to learn how to practice the religion and honor the Wiccan Deities.
While it is true that magic is among the practices shared by Wiccans, Wicca is not just about doing spells, etc. In fact many of us do very few spells on any sort of regular basis. If it's the magic that interests you rather than the religion, then you will want to look at other possibilities other than being Wiccan.
One possibility, given your interests, would be witchcraft. Witchcraft IS a form of magical practice which does not necessarily have any relationship to a particular religion. While some witches are Wiccan, that is not the case with all witches.
