Bi or nah?

I don't know if im bi or not. I mean i find attractive and watch gay porn sometimes, and i also find women attractive, in fact i have gf. But the thought of tying the knot with a man never cross my mind and will never be, because mostly of their personality; the biggest example is my dad and male population im my country is something...

So long story short, i find male body hot and sext but cant bear to be in a relationship with them, and i love women because of their personality and their hot.

*/genuine question and no harm intended. Im sorry if my wording of my situation is "homophobic", because i don't mean it that way.
