Given the issue of passability and TG/TS girls' general sensitivity to being too tall (as height is one of the clocking factors)....
How important is it that your partner is taller than you?
For me, I stand around 5'6 - just right, not too short, not too tall - but I still prefer guys to be at least 5'10 or above, so even when I wear heels, I am still not taller than him. 6'0 is my dream height in a man!

Plus people observing us will just see a typical short girl with a taller guy at her side and think nothing of it, while the tall girl/short guy duo tends to get a second glance.
