Poofandmook is completely right in that it’s none of your business. Then again, we’re on a question and answer site, so I am not really offended by your question. However, there are many people who would find such a probing question inappropriate. Due to the number of times you’ve said you’re sorry I hope you have been able to reflect on your action and learn something from this exchange,after all we’re all here to learn something new about ourselves and the world we live in :)
As I am not offended I will answer your question. To me and many scientists, sexuality is not a binary choice (either gay or straight), but more like a gradient from gay to straight. I have been floating around in the gradient all my life. I have been both with men and women. I have loved both men and women. Right now I’m in a long term relationship with a man who I love. We have a very healthy sex life and love sharing what we like with each other, including fantasies and porno. My partner hasn’t had any desire for a relationship with a man, and that’s perfectly fine with me. And he sure doesn’t have any issues with me exploring my sexuality either without or with him involved.
So to answer your question, I don’t really subscribe to a label, but for those who do, bisexual would probably fit closest. I do pleasure myself with pictures of girls. And guys. And all sorts of combinations therein :)
