IRL tall girls, why am I scared to talk to them???

I know this isn’t the traditional giantess/shrinking discussions in this thread but i will speak my mind regardless

As a 5’8 male with an insane giantess fantasy I can’t help but gravitate towards women who are taller than me, the taller the better, and the idea of finding someone taller than me would be a dream come true (ideally she would have a giantess fantasy too but well beggers can’t be picky)

But i don’t know why, i can never seem to get taller women as weird as it is. I swear i always get the gitters and get scared but the moment i meet someone else who might be my height or a little shorter, i swear I gain all the confidence in the world and its cruisy (I’m not saying I’m some insane womaniser and im some love island model, but guys help me how do i meet a woman who is like 5 inches taller than me and not get scared lol)
