Is it normal that i want a girl to use a strapon on me? does that make me gay?

i had a girlfriend who was Bi and liked to dominate girls with sex toys. I thought a'lot about it, after she left me for a lesbian go figure, and i wish she had done that to me. i get turned on when i watch porn involving a girl or a guy getting tied up, im not really sure if i'm Bi or gay or what.
