I teach bellydancing at MoveStudio, which is a Preston and Campbell. It's not that far if you take the Tollway. Check out www.movestudio.com. They also have exotic dance taught by Clarissa (more like stripping type dance with the high heeled shoes). In Frisco you can take bellydance from Sa'diyya. www.sadiyyadance.com.
If you decide to do the bellydance thing, there is certainly nothing wrong with wanting to learn how to do a sexy dance. Keep in mind, however, that bellydancing is a part of a particular cultural dance tradition and most instructors teach it from that viewpoint. The bottom line is to just have fun, feel comfortable with your body, and be beautiful!
