Hi Red,
Everybody has advice, but I believe example is more helpful, beginning with your own. What do you do? Dress only in private, under-dress, dress at night while driving, dress at conventions or in cities away from home, dress in public occasionally, frequently, constantly? Would you like to do so more often? More publicly? 24/7? Do you have a wardrobe or stash of other-gender clothing?
If you do any of these things even some of the time, or just think or fantasize about them, you are indeed a cross dresser. If you don't, you aren't. Now what do you want to do and how are going to get there?
If you decide to actively pursue cross dressing you should first be concerned with your own safety. After safety, your own comfort matters most. So unless you get off by being outrageous, you'll want to look relatively normal. To do that, you'll have to have an understanding of style, makeup, and gender-appropriate dress. If you don't, you'll need advice and guidance. If group you don't have a friend who enjoys helping you, your best bet is to find a local cross-dressing group.
You've probably noticed that I haven't asked what gender presentation you are or want to adopt.
Look around here and you'll find your people.
