Am I bisexual or straight (read description)

So I need help because I’m confused. I don’t know if I’m bisexual or not because some people say I’m not but I dated a transgender boy a few months ago and I didn’t care that he had lady parts I actually liked that about him. We had sex and I really liked it and all, but I can’t see myself having sex with a girl with more feminine looks (like me), I can only see myself with guys or transgender guys, sorry if this is a dumb question but my friends have been confusing me and I could use some more opinions.
