Am I gay? biual? straight? or just weird?

Your behaviour screams of ity, and a great discomfort with that fact. You don't need someone to define your uality for you, you can do that on your own. What you need is to be comfortable with your uality, your body, and what does and doesn't stimulate you. So long as what you do doesn't disrupt your relationship, isn't illegal, and is done between consenting adults, what's the problem?
