Bisexual or biromantic?

What’s the difference between the two.

I’m not exactly sure what I am and the internet hasn’t really helped me that much.

For me, I want to have a romantic relationship with either a girl, boy or really anyone else. (I guess I could also be Pan but someone said that since I’m still attracted to looks I’m still Bi. But also I’ve only ever had romantic feelings for people after I get to know them)

On a website there was also something about liking two genders but only one romantically and the other just kinda like sex? I guess. I’m not really sure.

But I would be open to a relationship and sex with gender.

Any ideas on what I am?
