Am i a gay or bi? Help me please.

Hi guys. I am 24 y old male. I am not sure about my sexual orientation. When i was 8 i remember keeping something in my ass and it felt superb. Then FF when i was 14, i started masturbation. I remember , i liked ass more than pussy, and i keep fapping for 3 -4 years until i saw pussy first time in porn. And honestly i didn't like the pussy that time. I used to masturbate stimulating prostate in anus by inserting something. I kissed a girl when i was 14, i got erection very hard. From age 19 to 24 i was not much attracted to girls. I never knew why. Now since 6 months, i want to have a gf, and i find girls attractive now.I have never been attracted to guys, however sometime i want to get my ass fucked. (And it maybe better if someone else do it).Now yesterday i went to see a girl after gathering courage,( i was a typical nice guy, plus lot of masturbation make one socially anxious, i am doing no fap 68 days so i got confidence). That girl tried everything but i didn't get erection. Then i said her to show her ass, and i rubbed my cock against her ass , immediately i got hard. But when i tried to insert in pussy it became too soft(in missionary). Maybe if she were in doggy that could help. But i felt disgusting, ( i once earlier too tried sex, but that time i didn't Even get hard.)Now tell me, was that only anxiety or something else. I don't like pussy, i like ass (i know it at least now). Even imaging a pussy don't give me any excitement, while ass can make me do anything.(i got high, but i dint like male ass,i like female for ass.)Please help me. I am totally mind fucked .
