Is it normal that i like bitter food?

I like food that tastes bitter. So far i dont know anyone who likes it too, but does anyone else like bitter food? I like those dark green vegetables cuz their bitter, and usually my friends cringe at the thought of eating them, and usually i would pretend that i hate them too, but I secretly dont mind eating them. My tolerance for bitterness is pretty high, i would say, i like bitter gourd, which is probs the mosy bitter vegetable there is.
