am i bisexual or pansexual?

i've never had the time to think considering i was labeled bisexual as soon as the gay community was kinda there but no one ever acknowledged it. i labeled myself as bisexual since i've never heard of a transgender when i was in the 7th grade. it wasn't until recently that i thought about it. like, i love the thought of dating a woman or a man but then i was questioned; would i date a woman/man that was born with a different gender?

my answer would be, yes. yes i would. without hesitation, i would date someone that was born of a different gender. it didn't matter if they had surgery to attach their counterparts to be more into the part of their transformation. if a woman had their male genital it wouldn't matter to me. if a man had their boobs and their birth genital then i wouldn't matter. 

but now that i'm searching everything up, some things don't make sense, i just wanna know so i don't look stupid when people ask me the same questions and correct me. it gets exhausting when i get questioned numerous times and fighting into thinking i wa sbisexual when i was actually pansexual since i heard a brief summary that its someone loves their lover no matter their gender but there were things that people added and i'm not really updated into the LGBTQ community. 
if someone see's this then please help a fellow sister out please.
