First of all, what type of porn you watch may have very little to do with your sexuality. The classic example is hetero men who like to watch lesbian porn. Less obvious is the case of gay men who like to watch hetero porn. Or hetero women who like to watch gay porn. There's a lot of variety there, and a lot of different reasons why people like to watch things that may or may not correspond to the sex life they actually want to engage in themselves.
Now, I do understand the stress that comes with a whole new period of self-discovery, especially after you've been through it already and thought you had it settled. But maybe you've already come up with the answer to that:

If the label of "pansexual" is becoming a problem for you, then drop the label. Maybe your sexuality will remain fluid for you for a long time. Maybe you're finally settling in the position you'll be for the rest of your life. It's hard to say, but my big rule of thumb with labels - whatever they may be - is that the second they become a problem instead of a source of support and comfort, throw them out the window. If you meet a guy tomorrow that you're attracted to, then great - go for it. Or if you meet a woman tomorrow whom you think is awesome, then go for that. But don't punish yourself because you decided to describe yourself a certain way in the past.
