Yes, you are heightist. You truly are.

Now, you are allowed to have your preferences. that's okay.

Many people won't date someone who is fat. That is fat phobic, but highly tolerated and accepted in dating culture.

Many people won't date someone a different skin color than them, that is racist.

Many people don't want to date someone is a different religion, for various reasons.

Many people won't date someone who has a certain bra size.

Many people won't date someone who isn't blond or other hair colors,

It's totally fine that you prefer tall men.

However, I just have to say here,

you needing to feel small compared to your male mate to make you feel feminime, could have some negative consequences.

For example, a large part of the male population is short. While there are some jerks and not good partners out there who are short, there are also many wonderful, good men who you are already shutting yourself off to. There could be someone who has the ability to make you very happy and be a good partner to you, and you will walk right by him.

If that's what's important to you, Height that's what's important, and that's okay. You don't have to justify yourself. But, there could be some wonderful potential relationships out there that you are choosing not to investigate because of the height thing. In other words, in being heightist, you are choosing to miss out on some potentially wonderful life experiences, it's your loss. That is your choice, and it's a free country, it's yours to make. I write this with total respect.
