Hey homie, it's really great to hear that you're blossoming out of your older views.

A couple thoughts:

I encourage you to think of sex as person-focused, instead of as a rigid set of things you're "into" or not. Porn is focused on "thing-ifying" acts and people's bodies. The things you do with people are personal, and it's easy to let porn confuse you!

All your "is this normal" questions are worth thinking about, but I don't think they're a big concern. It's fine to be uninterested in acts with one person, and you might find that you're interested in them with another person! As long as you're centering comfort, consent, and a healthy mentality, I don't think you have anything to worry about.

I've been to gay bars as an ostensibly straight person, and had positive experiences. I think it's a good idea to be cautious of encroaching on a safe space, and maybe just chill at the bar with a drink and a book for a bit while you get your bearings.

I think it's worth dropping the rigid self-categorization for a bit. You don't have to proactively announce what you consider your sexuality is, and you don't even need to put yourself in a box in your own mind. It's fine to be "exploring" or whatever for a bit. People change and develop, and it's ok to not worry about the details.
