The only thing I can really add here--but it's important and worth restating--is that you decide if you're straight, gay, or what. We can tell you what we think but it's really your call.
It's your privilege to discover what you like and decide how you act on it. It's your privilege to decide what labels you stick onto yourself and un-stick them if they don't fit anymore. It's not you that has to fit the label.
Be comfortable questioning who you are. Be comfortable looking for your own answers.
