I like tall guys and I always have, my SO is 6'3" and I'm 5'10" so I'm right on average height. I also like lots of other types and shapes of guys, too.
I don't think liking tall guys means I have a pathology or a problem. Just like ITW, I went to the web site and found it to be crappy but there wasn't anything to be concerned about. Macrophilia is a big broad definition and the issue here is about whether there is an obsession or fixation.
You haven't shared anything that makes me believe that this is true of you. But even if you had, people of different sizes, shapes, skin tones, etc. getting it on together can be pretty hot because of the contrasts and differences between them.
If you think that there is a link between your liking of big guys, or some large body-part, and your abuse situation, it might be worth exploring *that* rather than caring whether a web site declares you have a "condition" that it isn't clear to me at face value is even a problem.
Repeat after me "I will not attempt to self-diagnose myself using the Internet"
Do you have a therapist? If not, I really recommend getting one so you have someone to share these things with.
